Product Description
The ECG001B is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the ECG001B typically provides
22 dB of gain, +25 dBm Output IP3, and +12.5 dBm P1dB.
The ECG001B 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 ECG001B will work for other various applications
within the DC to 6 GHz frequency range such as CATV
and mobile wireless.

2. 3OIP measured with two tones at an output power of –1 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
