Product Description
The ECG040 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1 GHz, the ECG040B typically provides 15.8
dB of gain, +35 dBm Output IP3, and +18.5 dBm P1dB.
The ECG040 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 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 ECG040 will work for other various applications within
the DC to 4 GHz frequency range such as CATV and
mobile wireless.
