Datasheet SRF-2016 Datasheet (Stanford Microdevices)

Product Description

The Stanford Microdevices’ SRF-2016 is a multipurpose
demodulator RFIC capable of both quadrature demodula­tion or direct IF output. This device features switchable
gain control, high input P1dB, and excellent I/Q amplitude
and phase balance.

The SRF-2016 uses silicon germanium device technology
to yield a highly integrated RFIC for use in a variety of sys­tem applications. Use of this integrated device over stan­dard discrete implementations can result in lower
component count, less PCB space and higher transceiver
card yields.
