Product Description

The ECG014 is a high dynamic range driver amplifier in a

low-cost surface mount package. The InGaP/GaAs HBT is

able to achieve performance over a broad range with +39

dBm OIP3 and +23 dBm of compressed 1-dB power and is

housed in an industry standard SOT-89 SMT package. All

devices are 100% RF and DC tested.

The product is targeted for use as a gain block/driver

amplifier for various current and next generation wireless

technologies such as GPRS, GSM and CDMA, where high

linearity and medium power is required. In addition, the

ECG014 will work for numerous other applications within

the 50 to 2000 MHz frequency range.

1. Test conditions unless otherwise noted: 25

°C, Vsupply = +8V, in tuned application circuit with

Rbias = 30

Ω.

2. 3OIP measured with two tones at an output power of +9 dBm/tone separated by 1 MHz. The

suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule. The tuned

application circuit is tuned for optimum ACPR performance. An improvement in OIP3 of 2 to 3

dB can be achieved for tuning for optimum OIP3 (with slightly degraded ACPR performance).

3. This corresponds to the quiescent current or operating current under small-signal conditions.

4. This device requires a minimum 7 V power supply through a dropping resistor. 8 V and 30 ohms

are recommended for proper operation. Operation of the device directly to a 5 V supply could lead

to thermal damage to the device.
