Product Information
Product Features
Product Description
Functional Diagram
The AH312 / ECP200 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.
• 400 – 2300 MHz
• +33 dBm P1dB
• +51 dBm Output IP3
• 18 dB Gain @ 900 MHz
• 11 dB Gain @ 1960 MHz
• Single Positive Supply (+5V)

The AH312 / ECP200 is targeted for use as a driver
amplifier in wireless infrastructure where high linearity and
medium power is required. An internal active bias allows
the AH312 to maintain high linearity over temperature and
operate directly off a single +5V supply. This combination
makes the device an excellent candidate for transceiver line
cards in current and next generation multi-carrier 3G base
stations.

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.)
