General Description
TriQuint’s TGA2618 is a Ku-band Low Noise Amplifier fabricated on TriQuint’s TQPHT15 0.15 μm GaAs pHEMT process. The TGA2618 operates from 16 to 18 GHz and typically provides 6 dBm P1dB, 28 dB of small signal gain and 13 dBm OTOI with 2.3 dB NF.
The TGA2618 is ideally suited to support both radar and satellite communications as either an LNA or a general purpose gain block.
Both RF ports have intergraded DC blocking caps and are fully matched to 50 ohms allowing for simple system integration.
Lead-free and RoHS compliant
Evaluation Boards are available upon request.
