Product Summary

The bgy145a is a VHF power amplifier module. The bgy145a is designed for use in transmitters of mobile communications equipment powered by vehicles with 12.5V battery suppliers. The bgy145a is a two-stage transistor amplifier and consists of two RF npn transistors mounted on a ceramic substrate, togather with surface mounted components that make up the matching and bias circuits.
