SiGe HBT IF Receiver/Demodulator Line
The SRF-2016 extends Stanford Microdevices' offering of SiGe IF receiver/demodulators and complements the already-released 65 to 300 MHz SRF-1016. The new SRF-2016 targets frequencies in the 200 to 600 MHz range. It is packaged in an industry-standard 16-pin exposed-pad TSSOP plastic package, ideal for applications where space is at a premium.
Key features of both the SRF-1016 and the SRF-2016 are their exceptional amplitude and phase balance at the baseband outputs. Amplitude balance is typically better than 0.1 dB, while phase balance is typically better than 1 degree. The gain of both parts can be conveniently controlled with CMOS logic levels, and both are specified for use with a single +5 V power supply.
The SRF-2016 provides typical conversion gains of approximately -5.5 dB, +14 dB and +33 dB, with an output 1 dB compression point of +7 dBm at all gain settings. The noise figure at high gain is less than 6 dB and all ports are internally matched to 50 ohms. The SRF-1016 provides typical conversion gains of approximately -5.5 dB, +13 dB and +32 dB, with an output 1 dB compression point of +5.5 dBm at all gain settings.
