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 con-

sists 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 single-

ended if the other input is connected to ground through an AC short such as a 1000pF capacitor. This typically results in

slightly lower input P

1dB

The two matched mixers are configured with the quadrature LO generator to provide in-phase and quadrature baseband out-

puts. These can be fed through ADCs to a DSP engine, or can be fed into a low frequency 90° hybrid for image rejection. Alter-

natively, 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 50Ω impedance. The package (and in the case of the input port, the parallel L-R net-

work) 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 frequen-

cies.

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:

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, pref-

erably 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 V

pins are not internally connected, so all must be connected together externally with

the specified decoupling capacitors.

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

1dB

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 var-

ies less than 0.05dB and 0.5° over temperature (-40 to +85C).
