Two Bidirectional PA Variants on a Common PCB

One PCB platform supports bidirectional PA variants for 2.4 GHz ISM and 1.2–1.4 GHz L-band UAV communications.

E-REON began assembly and testing of a bidirectional power-amplifier platform designed to support two different products on a common PCB.

With only minor bill-of-material changes involving capacitors and two SAW filters, the board can be configured as either a 2.4 GHz ISM-band bidirectional PA or a 1.2–1.4 GHz L-band bidirectional amplifier for UAV communications.
