... Power Amplifier (PA) driver with superior output power, low noise, linearity, and efficiency. The device provides a 2.0 dB Noise Figure (NF) and Output Compression Point (OP1dB) of +22.3 dBm, making the SKY65081-70LF ideal for use in the driver stage of infrastructure transmit chains. The SKY65081-70LF uses low-cost Surface-Mount Technology (SMT) in the form of a 4-pin, 2 ...

... RF_OUT 4 GND 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 following design considerations are general in nature and must be followed regardless of final use or configuration. 1. Paths to ground should be made as short as possible. 2. The ground pad of the SKY65081-70LF power amplifier has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the amplifier ...
