Product Description

The ECG050 is a general-purpose buffer amplifier that

offers high dynamic range in a low-cost surface-mount

package. At 1000 MHz, the ECG050 typically provides 19

dB of gain, +34 dBm Output IP3, and +19 dBm P1dB.

The ECG050 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.

The ECG050 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 ECG050 will work for other various applications within

the DC to 4 GHz frequency range such as CATV and fixed

wireless.
