TC3843A
DESCRIPTION
The TC3843A is a single-bias with 50 ohm matched GaAs FET. It is designed for low cost, high volume, applied
for 1710~1785 MHz low noise amplifiers. It provides noise figure of 1.1 dB, gain of 16 dB and P1dB of 24 dBm,
typically. The single positive drain bias is 6 V and the typical drain-source current is 160 mA. The device is
packaged in a copper based ceramic 10-pin SMT packages. The copper based carrier of the package allows direct
soldering of the device to the PCB.
