Product Description
The ECG055 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the ECG055 typically provides
20 dB of gain, +34 dBm Output IP3, and +18 dBm P1dB.
The ECG055 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 ECG055 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 ECG055 will work for other
various applications within the DC to 3 GHz frequency
range such as CATV and fixed wireless.

1. Test conditions unless otherwise noted: 25º C, Supply Voltage = +6 V, Rbias = 18 , 50 System.
2. 3OIP measured with two tones at an output power of +4 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
