DS101122 SRF-2016(Z) The SRF-2016 is a variable gain I-Q demodulator designed for use in receiver IF sections, as shown in the figure below. It consists of five subcircuits: two cascaded switched gain stages, a matched pair of mixers, and a LO quadrature generator. This part is also available in a higher frequency version, the SRF-1016. The gain stages are broadband differential amplifiers each with a digital control pin to set the gain. The gain control pins act independently of each other. Since the amplifiers have approximately the same gain, setting GC1 high and GC2 low results in approximately the same gain as setting GC1 low and GC2 high. The former setting is preferred because it offers better noise figure. The IF input is differential with internal bias circuitry to set the common mode voltage. The use of blocking capacitors to facilitate AC coupling is highly recommended to avoid changing the common mode voltage. Either input may be driven singleended if the other input is connected to ground through an AC short such as a 1000pF capacitor. This typically results in slightly lower input P1dB. The two matched mixers are configured with the quadrature LO generator to provide in-phase and quadrature baseband outputs. These can be fed through ADCs to a DSP engine, or can be fed into a low frequency 90° hybrid for image rejection. Alternatively, the IF signal can be extracted from the BBI port by injecting DC into the LO port. RF Filter IF Filter SRF 2016 BB Filter I ADC BB Filter Q ADC NE W LNA DE SI GN S The LO and IF ports offer a differential 50 impedance. The package (and in the case of the input port, the parallel L-R network) adds inductance that tends to degrade return loss. This can easily be matched out with a series capacitor. The 8.2pF capacitor on the evaluation board is appropriate for 400MHz operation; larger capacitors should be used for lower frequencies. Typical use for the SRF-2016 in a receiver employing digital I/Q demodulation. The SRF-2016 has high gain at UHF frequencies, so instability can result if there is poor power supply decoupling or undesired coupling from the input to the output. The following considerations should be observed when laying out a PC board: FO R Follow the general layout of the evaluation board, keeping the power supply decoupling capacitors as close to the package as possible. The back of the package, the two ground pins and the decoupling capacitors should connect directly to ground, preferably to a large dedicated ground plane. Use the parallel L-R circuits on the input pins. Ensure that the input signal tracks are routed far from the output tracks. The VCC pins are not internally connected, so all must be connected together externally with the specified decoupling capacitors. NO T The figures on page 4 illustrate a typical SRF-2016’s performance with respect to temperature. Note that these numbers include the effect of the R-L network in the IF port. The frequency response of the IF and LO ports is dominated by the L-R network on the input. When de-embedded, the gain and P1dB response is within 0.5dB from 200MHz to 600MHz. The SRF-2016 features immunity from changes in LO power. The gain typically changes by less than 0.6dB over a 6dB range of LO power. Also note the excellent I/Q balance, which typically falls within 0.15dB and 1.5° from 200MHz to 600MHz, and varies less than 0.05dB and 0.5° over temperature (-40 to +85C).

Note that heat is removed from the part via the heat slug, so this slug must be properly soldered to a copper plane under the part. Evaluation boards are available for this device and a description of the board are shown on page 6. Note that the evaluation board uses baluns on the I/Q outputs, and these baluns limit the low frequency response of the device. For true baseband operation, the baluns should be removed, and the differential signals used directly.
