InGaP HBT Gain Block
Product Description
The ECG008 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the ECG008 typically provides 15
dB of gain, +40 dBm Output IP3, and +24 dBm P1dB.
The ECG008 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 low
cost, surface-mountable SOT-89 package. The ECG008 is
also available in a 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 ECG008 will work for other various applications within
the DC to 4 GHz frequency range such as CATV and fixed
wireless.
