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
.
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.
