Product Description
The ECG005 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the ECG005 typically provides
19.5 dB of gain, +34 dBm Output IP3, and +18 dBm P1dB.
The ECG005 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 low-cost,
surface-mountable plastic SOT-86 and SOT-89 packages.
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 ECG005 will work for other various applications within
the DC to 4 GHz frequency range such as CATV and fixed
wireless.
