Technical Description
The SKY85736-11 is comprised of a high-power 5 GHz PA, a
5 GHz LNA, and a broadband SPDT switch. The device is fully-
matched, and requires few external components for optimal
performance, which makes it ideal for small portable/mobile
applications. The FEM provides up to +31 dB of transmit gain
over the frequency band. The LNA supports an enable/disable
mode for power savings when not in receive mode and a bypass
function for increased receive dynamic range. The PA can be shut
off using the PA_EN signal (pin 4).
The low-loss broadband switch provides the T/R switching
function on the SKY85736-11 and has a 1 dB output compression
point (OP1dB) of approximately +30 dBm.
Electrical and Mechanical Specifications
