Technical Description
The SKY65080-70LF 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 1500 to 2500 MHz.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
described in Table 1. The absolute maximum ratings of the
SKY65080-70LF are provided in Table 2. The recommended
operating conditions are specified in Table 3 and electrical
specifications are provided in Table 4.
Typical performance characteristics of the SKY65080-70LF are
illustrated in Figures 3 through 9.
