The TriQuint ECG003B-G is a general-purpose buffer amplifier that offers high dynamic range in a low-cost surface-mount package. At 1000 MHz, the ECG003B-G typically provides 20 dB of gain, +39 dBm Output IP3, and +24 dBm P1dB.

The ECG003B-G consists of Darlington pair amplifiers using the high reliability InGaP / GaAs HBT process technology and only requires DC-blocking capacitors, a bias resistor and an inductive RF choke for operation. The device is ideal for wireless applications and is available in a lowcost, surface-mount lead-free / green / RoHS-compliant SOT-89 package. All devices are 100% RF and DC tested.

The broadband MMIC amplifier can be directly applied to various current and next generation wireless technologies such as GPRS, GSM, CDMA, and W-CDMA. In addition, the ECG003B-G will work for other various applications within the DC to 6 GHz frequency range such as CATV and mobile wireless.
