Product Features
* 60 - 3500 MHz * +24.7 dBm P1dB * +40.5 dBm Output IP3 * 20.4 dB Gain @ 900 MHz * 16.5 dB Gain @ 1900 MHz * +5V Single Positive Supply * Lead-free/Green/RoHScompliant SOT-89 Package
The Communications Edge TM Product Information
1/4 Watt, High Linearity InGaP HBT Amplifier
Product Description
The AH118 is a high dynamic range driver amplifier in a low-cost surface mount package. The InGaP/GaAs HBT is able to achieve high performance across a broad range with +40.5 dBm OIP3 and +24.7 dBm of compressed 1dB power. The AH118 is available in a lead-free/green/RoHScompliant SOT-89 package. All devices are 100% RF and DC tested. The AH118 is targeted for use as a driver amplifier in wireless infrastructure where high linearity and medium power is required. Internal biasing allows the AH118 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.

Notes: The gain for the unmatched device in 50 ohm system is shown as the trace in black color. For a tuned circuit for a particular frequency, it is expected that actual gain will be higher, up to the maximum stable gain. The maximum stable gain is shown in the dashed red line. The impedance plots are shown from 50 - 6000 MHz, with markers placed at 0.5 - 6.0 GHz in 0.5 GHz increments.

All passive components are of size 0603 unless otherwise noted. The diode D1 is used as over-voltage protection on the evaluation boards. It is not specifically required in the final circuit layout in a system using a DC regulator. Component R1 is shown in the silkscreen but is not used for this configuration. ID=D1 5.6 V

AH118
The Communications Edge TM Product Information
1/4 Watt, High Linearity InGaP HBT Amplifier
This package is lead-free/Green/RoHS-compliant. It is compatible with both lead-free (maximum 260 C reflow temperature) and leaded (maximum 245 C reflow temperature) soldering processes. The plating material on the leads is NiPdAu.
AH118-89G Mechanical Information
Outline Drawing
Product Marking
The component will be marked with an "AH118G" designator with an alphanumeric lot code on the top surface of the package. The obsolete tin-lead package is marked with an "AH118" or "E099" designator followed by an alphanumeric lot code. Tape and reel specifications for this part are located on the website in the "Application Notes" section.

Mounting Config. Notes
1. Ground / thermal vias are critical for the proper performance of this device. Vias should use a .35mm (#80 / .0135") diameter drill and have a final plated thru diameter of .25 mm (.010"). 2. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance. 3. Mounting screws can be added near the part to fasten the board to a heatsink. Ensure that the ground / thermal via region contacts the heatsink. 4. Do not put solder mask on the backside of the PC board in the region where the board contacts the heatsink. 5. RF trace width depends upon the PC board material and construction. 6. Use 1 oz. Copper minimum. 7. All dimensions are in millimeters (inches). Angles are in degrees.

Notes: 1. The amplifier can be operated at 105 C case temperature for up to 1000 hours over its lifetime without degradation in performance and will not degrade device operation at the recommended maximum 85 C case temperature for the rest of its lifetime. 2. The thermal resistance is referenced from the junction-to-case at a case temperature of 85 C. 3. This corresponds to the typical biasing condition of +5V, 160 mA at an 85C case temperature. A minimum MTTF of 1 million hours is achieved for junction temperatures below 247 C.
