Technical Description
The SKY65081-70LF is a single stage, low-noise PA that operates
with a single 5 V power supply connected through an RF choke
(inductor L1) to the output signal (pin 3). The bias current is set by
the on-chip active bias composed of current mirror and reference
voltage transistors, which allow excellent gain tracking over
temperature and voltage variations. The device is externally RF
matched using surface mount components to facilitate operation
over a frequency range of 2000 to 3000 MHz.
