DESCRIPTION AND APPLICATIONS
This evaluation board is a single-ended, dual biased, power amplifier. It is reactively
matched at a frequency of 1.85 GHz. The active device is a Filtronic FP750SOT343; a
double-heterojunction, 750
µm
gate periphery PHEMT. The connectors are SMA jacks
soldered to a 30 mil thick FR4 PC Board. Both RF ports are DC-decoupled.
Biasing can be applied through test clips (E-Z hooks) at the bias vias on the bottom of the
board. A negative gate voltage is required for current limiting. Ground connection should
be established prior to the gate and drain bias connections. This board is thin and flexible,
so caution should be exercised when connecting it to coaxial cables.
