Product Information  
Product Features  
Product Description  
Functional Diagram  
The AH312 is a high dynamic range driver amplifier in a  
low-cost surface mount package. The InGaP/GaAs HBT is  
able to achieve high performance for various narrowband-  
tuned application circuits with up to +49 dBm OIP3 and  
+33 dBm of compressed 1dB power. It is housed in a lead-  
free/green/RoHS-compliant SOIC-8 package. All devices are  
100% RF and DC tested.

4. Typical parameters reflect performance in a tuned application circuit at +25° C.  
1. Test conditions unless otherwise noted: 25ºC, +5V Vsupply, 2140 MHz, in tuned application circuit.  
2. 3OIP measured with two tones at an output power of +17 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. This corresponds to the quiescent current or operating current under small-signal conditions into  
pins 6, 7, and 8. It is expected that the current can increase by an additional 200 mA at P1dB. Pin  
1 is used as a reference voltage for the internal biasing circuitry. It is expected that Pin 1 will pull  
22mA of current when used with a series bias resistor of R1=15Ω. (ie. total device current  
typically will be 822 mA.)
