CV111-1 PCS/DCS-band High Linearity Downconverter The Communications Edge TM Product Information Product Features • High dynamic range downconverter with integrated LO, IF, & RF amps Product Description The CV111-1 is a high linearity downconverter designed to meet the demanding issues for performance, functionality, and cost goals of current and next generation mobile infrastructure basestations. It provides high dynamic range performance in a low profile surface-mount leadless package that measures 6 x 6 mm square. Functionality includes RF amplification, frequency conversion and IF amplification, while an integrated LO driver amplifier powers the passive mixer. The MCM is implemented with reliable and mature GaAs MESFET and InGaP HBT technology. Typical applications include frequency down conversion, modulation and demodulation for receivers used in CDMA/GSM/TDMA, CDMA2000, W-CDMA, GPRS, and EDGE 2.5G mobile infrastructure technologies for PCS / DCS frequency bands.

Specifications when using the application specific circuit (shown on page 3) with a low side LO = 0 dBm in a downconverting application over the operating case temperature range. 2. The IF bandwidth of the converter is defined as 15% around any center frequency in its operating IF frequency range. The bandwidth is determined with external components. Specifications are valid around the total ±7.5% bandwidth. ie. with a center frequency of 240 MHz, the specifications are valid from 240 ± 18 MHz. 3. Assumes the supply voltage = +5 V. OIP3 is measured with ∆f = 1 MHz with IFout = 5 dBm / tone. 4. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies. 5. The maximum junction temperature ensures a minimum MTBF rating of 1 million hours of usage.

There are various placeholders for chip components in the circuit schematic so that a common PCB can be used for all WJ single-branch converters. Additional placeholders for other optional functions such as filtering are also included. RF / IF Amplifier Matching: The RF amplifier requires a matching element (C12) for optimal gain and input return loss performance. The IF amplifier requires matching elements to optimize the performance of the amplifier to the desired IF center frequency. Since IF bandwidths are typically on the order of 5 to 10%, a simple two element matching network, in the form of either a high-pass or low-pass filter structure, is sufficient to match the MMIC IF amplifier over these narrow bandwidths. Proper component values for other IF center frequencies can be provided by emailing to applications.engineering@wj.com. RF Bandpass Filtering: Bandpass filtering is recommended to achieve the best noise figure performance with the downconverter. The bandpass filter, implemented with a SAW filter on the application circuit, allows for the suppression of noise from the image frequency. It is permissible to not use a filter and use a 2 dB pad with R6, R7, and R16 instead with slightly degraded noise figure performance. External Diplexer: This is only used with the cellular-band CV products. The mixer performs the diplexing internally for the CV111-1; therefore the components shown in the diplexer section should be loaded as follows: C2 = C14 = 0 Ω. IF and LO Lowpass Filtering (optional): Filtering of unwanted RF and LO signals are typically performed in the IF chain. This filtering function may be realized using lumped elements; placeholders (L9, C21, C22) are provided in the application circuit to allow for lumped-element filtering to be implemented if desired. The LO lowpass filter is used only in the cellular-band CV products; it should not be used for this product. L1 should be loaded with a 0 Ω jumper. DC biasing: DC bias must be provided for the RF, LO and IF amplifiers in the converter. R1 sets the operating current for the last stage of the LO amplifier and is chosen to optimize the mixer LO drive level. Proper RF chokes and bypass capacitors are chosen for proper amplifier biasing at the intended frequency of operation. The “+5 V” dc bias should be supplied directly from a voltage regulator.
