Product Description
The ECG002 is a general-purpose buffer amplifier that
offers high dynamic range in a low-cost surface-mount
package. At 1000 MHz, the ECG002 typically provides 20
dB of gain, +29 dBm Output IP3, and +15.5 dBm P1dB.
The ECG002 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 lead-free/green/RoHS-compliant
SOT-363, 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 ECG002 will work for other various applications within
the DC to 6 GHz frequency range such as CATV and
mobile wireless.

1. Test conditions unless otherwise noted: 25 C, Supply Voltage = +5 V, Rbias = 24
Ω, 50 Ω System.
2. 3OIP measured with two tones at an output power of +2 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. Large-signal gain is tested with an input power level of -3 dBm.
