GENERAL DESCRIPTION The ADMV1014 is a silicon germanium (SiGe), wideband, microwave downconverter optimized for point to point microwave radio designs operating in the 24 GHz to 44 GHz frequency range. The downconverter offers two modes of frequency translation. The device is capable of direct quadrature demodulation to baseband inphase (I)/quadrature (Q) output signals, as well as image rejection downconversion to a complex intermediate frequency (IF) output carrier frequency. The baseband outputs can be dc-coupled, or, more typically, the I/Q outputs are ac-coupled with a sufficiently low high-pass corner frequency to ensure adequate demodulation accuracy. The serial port interface (SPI) allows fine adjustment of the quadrature phase to allow the user to optimize I/Q demodulation performance. Alternatively, the baseband I/Q outputs can be disabled, and the I/Q signals can be passed through an on-chip active balun to Rev. A provide two single-ended complex IF outputs anywhere between 800 MHz and 6000 MHz. When used as an image rejecting downconverter, the unwanted image term is typically suppressed to better than 30 dBc below the wanted sideband. The ADMV1014 offers a flexible local oscillator (LO) system, including a frequency quadruple option allowing up to a 41 GHz range of LO input frequencies to cover a radio frequency (RF) input range as wide as 24 GHz to 44 GHz. A square law power detector is provided to allow monitoring of the power levels at the mixer inputs. The detector output provides closed-loop control of the RF input variable attenuator through an external op amp error integrator circuit option. The ADMV1014 downconverter comes in a compact, thermally enhanced, 5 mm × 5 mm LGA package. The ADMV1014 operates over the −40°C to +85°C case temperature range.

See Figure 1 for a functional block diagram of the device. The ADMV1014 digital settings are controlled via the SPI. The ADMV1014 has two modes of operation:   Baseband quadrature demodulation (I/Q mode) Image reject I/Q downconversion (IF mode) START-UP SEQUENCE The ADMV1014 SPI settings require its default settings to be changed during startup for optimum performance. To use the SPI, toggle the RST pin to logic low and then logic high to perform a hard reset before starting up the device. Set Register 0x0B to 0x727C after every power-up or reset. Set Register 0x03, Bits[13:12] to 11 after every power-up or reset. BASEBAND QUADRATURE DEMODULATION (I/Q MODE) In I/Q mode, the output impedance of the baseband I/Q ports is 100 Ω differential. These outputs are designed to be loaded to a dc-coupled, differential, 100 Ω load. I_P and I_N are the differential baseband I outputs. Q_P and Q_N are the differential baseband Q outputs. To set the ADMV1014 in I/Q mode, set BB_AMP_PD (Register 0x03, Bit 8) to 0 and set IF_AMP_PD (Register 0x03, Bit 11) to 1. The baseband I/Q ports are designed to operate from dc to 6.0 GHz at each I and Q channel. The BB output VCM can be changed from 1.05 V to 1.85 V. To change the VCM, set BB_SWITCH_HIGH_LOW_COMMMON (Register 0x0A, Bit 0) to be the opposite of Register 0x0A, Bit 6. Also, set the MIXER_VGATE bit field (Register 0x07, Bits[15:9]) and the BB_AMP_REF_GEN bit field (Register 0x0A, Bits[6:3]) based on Table 6. Table 6 provides the correct setting for these bit fields vs. the required common-mode voltage. The VCM can be further adjusted on each I or Q channel by ±15 mV by setting the BB_AMP_OFFSET_I bit field (Register 0x09, Bits[4:0]) and the BB_AMP_OFFSET_Q bit field (Register 0x09, Bits[9:5]) for each VCM setting shown in Table 6. The most significant bit (MSB) for each bit field is the sign bit. When the MSB is 1, the values of the four lower bits are positive. When the MSB is 0, the values of the four lower bits are negative. These bits also offer input IP2 and common-mode rejection optimization. The BB I/Q section of the ADMV1014 also features a baseband amplifier with a digital attenuator that is controlled by setting the BB_AMP_GAIN_CTRL bit field (Register 0x0A, Bits[2:1]). Figure 44, Figure 45, and Figure 46 show the performance of the baseband digital attenuator. The Baseband Quadrature Demodulation to Very Low Frequencies section shows the baseband performance to very low demodulation frequencies. Table 6.

The IF outputs are quadrature to each other, 50 Ω single-ended, and are internally ac coupled. IF_I and IF_Q are the quadrature IF outputs. An external 90° hybrid is required to select the appropriate sideband. path can switch from differential to single-ended operation by setting the QUAD_SE_MODE bits (Register 0x04, Bits[9:6]). See the Performance Between Differential vs. Single-Ended LO Input section for more information. Figure 102 shows a block diagram of the LO path. To configure the ADMV1014 in IF mode, set BB_AMP_PD (Register 0x03, Bit 8) to 1 and set IF_AMP_PD (Register 0x03, Bit 11) to 0 DETECTOR The ADMV1014 features a square law detector that produces a voltage linearly, according to the square of the RF voltage output from the low noise amplifier. The detector can be enabled by setting the DET_EN bit (Register 0x03, Bit 6) to 0. The detector can be turned off by setting this bit to 1. The detector linear range can be adjusted by setting the DET_PROG bit field (Register 0x07, Bits[6:0]). These ranges are specified based on the input power into the detector coming from the output of the low noise amplifier. Each DET_PROG setting offers an approximate 20 dB of ±1 dB dynamic range based on a twopoint linear regression from an ideal line for one temperature at each DET_PROG setting. See Figure 89 to Figure 91 for more performance information of the detector. LO INPUT PATH The LO input path operates from 5.4 GHz to 10.25 GHz with an LO amplitude range of −6 dBm to +6 dBm. The LO has an internal quadrupler (×4) and a programmable band-pass filter. The LO band-pass filter is programmable using QUAD_FILTERS (Register 0x04 Bits[3:0]). See the Performance at Different Quad Filter Settings section for more information on the QUAD_FILTERS settings. The LO path can operate either differentially or single-ended (SE). LOIP and LOIN are the inputs to the LO path. The LO AMP LO_P ×4 4 × LO_N 4 × LO_P 17172-105 Each IF output features an amplifier with a digital attenuator. The digital attenuator can be adjusted using fine or coarse steps. The coarse steps for the IF_I can be adjusted using the IF_AMP_ COARSE_GAIN_I bit field (Register 0x08, Bits[11:8]). The coarse steps for the IF_Q can be adjusted using the IF_AMP_COARSE_ GAIN_Q bit field (Register 0x09, Bits[15:12]). Each course gain bit field has five settings. The fine steps for IF_I can be adjusted using the IF_AMP_FINE_GAIN_I bit field (Register 0x08, Bits[3:0]). The fine steps for the IF_Q can be adjusted using the IF_AMP_FINE_GAIN_Q bit field (Register 0x08, Bits[7:4]). Figure 77 to Figure 82 show the performance of these four bit fields. LO_N Figure 102. LO Path Block Diagram Enable the quadrupler by setting the QUAD_IBIAS_PD bit (Register 0x03, Bit 7) to 0 and the QUAD_BG_PD bit (Register 0x03, Bit 9) to 0. To power down the quadrupler, set both of these bits to 1. An unwanted image can be downconverted from the quadrature error in generating the quadrature LO signals. Deviation from ideal quadrature (that is, total image rejection and no image tone is downconverted) on these signals limits the amount of achievable image rejection. The ADMV1014 offers about 25° of quadrature phase adjustment in the LO path quadrature signals. Make these adjustments through the LOAMP_PH_ADJ_I_FINE bits (Register 0x05, Bits[15:9]) and the LOAMP_PH_ADJ_Q_FINE (Register 0x05, Bits[8:2]) bits. These bits reject the unwanted sideband signal. In IF mode amplitude adjustments can be made to the complex outputs via IF_AMP_FINE_GAIN_Q (Register 0x08, Bits[7:4]) and IF_AMP_FINE_GAIN_I (Register 0x08, Bits[3:0]) to further reduce the unwanted sideband. POWER-DOWN The SPI of the ADMV1014 allows the user to power down device circuits and reduce power consumption. There are two power-down modes: band gap power-down mode (BG_PD) and individual power-down circuits mode. The BG_PD bit (Register 0x03, Bit 5) and the QUAD_BG_PD bit (Register 0x03, Bit 9) power down the band gap circuit. The QUAD_IBIAS_PD bit (Register 0x03, Bit 7) and the IBIAS_PD bit (Register 0x03, Bit 14) power down the specific circuits. Table 7 shows the circuits that are controlled by their related power-down bit, the typical power savings, and the latency requirement to power the circuits back up. Rev.
