Note 1: To achieve 20 dB of port match, the parasitic inductance of the package, board, and L4, L5 must be matched out at the center frequency with a series capacitor. Note 2: To achieve 20 dB port match above 100 MHz, the parasitic inductance of the package must be matched out.

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-2016. 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 differ- ential 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 single- ended if the other input is connected to ground through an AC short such as a 1000 pF capacitor. This typically results in slightly lower input P1dB. The two matched mixers are configured with the quadra- ture 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 degree hybrid for image rejection. Alternatively, the IF signal can be extracted from the BBI port by injecting DC into the LO port. The LO and IF ports offer a differential 50 ohm 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 capaci- tor. The 27 pF capacitor on the evaluation board is appro- priate for 200 MHz operation; larger capacitors should be used for lower frequencies. The SRF-1016 has high gain at UHF frequencies, so insta- bility can result if there is poor power supply decoupling or undesired coupling from the input to the output. The follow- ing considerations should be observed when laying out a PC board:
- Follow the general layout of the evaluation board, keep- ing 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 decou- pling capacitors. The figures on page 4 illustrate a typical SRF-1016’s per- formance 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 domi- nated by the L-R network on the input. When de-embed- ded, the gain and P1dB response is within 0.5 dB from 65 MHz to 300 MHz. The SRF-1016 features immunity from changes in LO power. The gain typically changes by less than 0.6 dB over a 6 dB range of LO power. Also note the excellent I/Q bal- ance, which typically falls within 0.1 dB and 1 degree from 65 MHz to 300 MHz, and varies less than 0.05 dB and 0.5 degree over temperature (-40 to +85C). The package dimensions are shown on page 5. 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 is 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.
