GND
The ECG005B is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the ECG005B typically provides
22.1 dB of gain, +34 dBm Output IP3, and +18 dBm P1dB.
• DC – 4 GHz

• +18 dBm P1dB at 1 GHz
• +34 dBm OIP3 at 1 GHz
• 22.1 dB Gain at 1 GHz
• 3.3 dB Noise Figure at 2 GHz
The ECG005B 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 ECG005B will work for other various applications
within the DC to 4 GHz frequency range such as CATV
and mobile wireless.
