Product Description

The AH110 / 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. It is housed in a lead-

free/green/RoHS-compliant 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

AH110 / 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.
