NGA-486

DC-5 GHz, Cascadable

InGaP/GaAs HBT MMIC Amplifier

Product Features

• High Gain : 14.1 dB at 1950 MHz

• Cascadable 50 Ohm

• Patented InGaP Technology

• Operates From Single Supply

• Low Thermal Resistance Package

Stanford Microdevices’ NGA-486 is a high performance InGaP/

GaAs Heterojunction Bipolar Transistor MMIC Amplifier. A

Darlington configuration designed with InGaP process

technology provides broadband performance up to 5 GHz with

excellent thermal perfomance. The heterojunction increases

breakdown voltage and minimizes leakage current between

junctions. Cancellation of emitter junction non-linearities results

in higher suppression of intermodulation products. At 850 Mhz

and 80mA , the NGA-486 typically provides +39.5 dBm output

IP3, 14.8 dB of gain, and +19 dBm of 1dB compressed power

using a single positive voltage supply. Only 2 DC-blocking

capacitors, a bias resistor and an optional RF choke are required

for operation.
