ECG003B-G — Overview
ECG003B-G by Qorvo is a component in the DC-6000 MHz Cascadable Gain Block category, supplied by Shenzhen Jinteng Electronics Technology Co., Ltd. (JTDZ Tech) — an independent distributor serving OEMs, ODMs and EMS providers worldwide.
The ECG003B-G is a DC to 6 GHz cascadable gain block built from Darlington-pair amplifiers in an InGaP/GaAs HBT process, delivering 20 dB gain, +24 dBm P1dB and +39 dBm OIP3 at 1 GHz. It is internally matched to 50 ohm and needs only DC-blocking capacitors, a bias resistor and an RF choke. It is now obsolete, available from independent stock.
