The SLIM-RFA-1 is a Dual Amplifier, designed for
frequencies between 1 GHz and 2 GHz. Each Buffer Amplifier will provide
approximately 0 dB gain. The main purpose of the amplifier is not to
provide gain, but reverse isolation. The reverse isolation (S12) should
be about -38 dB. This module was developed with the PWB-RFA as the core
design. Click to see the PWB-RFA Web Page.
It should be noted that this buffer amplifier was
designed with the intention of using the MMIC Amplifier (U1 or U2) in
saturation, (it is not operated within its linear region). Its output
is intended to drive a mixer's L port. For linear operation, the input
signal should have a maximum power level of +4 dBm.
