AH116 The Communications Edge TM 1/2 Watt, High Linearity InGaP HBT Amplifier Product Features Product Information Product Description • 800 – 1000 MHz • +28 dBm P1dB • +42 dBm Output IP3 • 17 dB Gain @ 900 MHz • Single Positive Supply (+5 V) • MTTF >100 Years Functional Diagram The AH116 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 +42 dBm OIP3 and +28 dBm of compressed 1-dB power and is housed in an industry standard SOIC-8 SMT package. All devices are 100% RF and DC tested. The product is targeted for use as driver amplifiers for wireless infrastructure where high linearity and medium power is required. The internal active bias allows the AH116 to maintain high linearity over temperature and operate directly off a +5 V supply. This combination makes the device an excellent fit for transceiver line cards and power amplifiers in current and next generation multi-carrier 3G base stations. • SOIC-8 SMT Package Applications • Mobile Infrastructure • Final Stage Amplifier for Repeaters 1 8 2 7 3 6 4 5 Function Vref Input / Base Output / Collector Vbias GND N/C or GND Pin No. 1 3 6, 7 8 Backside 2, 4, 5 Specifications Parameters Units Min Typ Max Frequency Range S21 - Gain S11 - Input R.L.

ESD / MSL Information ESD Rating: Class 1B Value: Passes at between 500 and 1000V Test: Human Body Model (HBM) Standard: JEDEC Standard JESD22-A114 Land Pattern MSL Rating: Level 3 at +240 °C convection reflow Standard: JEDEC Standard J-STD-020A Mounting Config. Notes Thermal Specifications Rating Operating Case Temperature Thermal Resistance1, Rth Junction Temperature2, Tjc -40 to +85° C 62° C / W 162 °C Notes: 1. The thermal resistance is referenced from the junction-to-case at a case temperature of 85° C. Tjc is a function of the voltage at pins 6 and 7 and the current applied to pins 6, 7, and 8 and can be calculated by: Tjc = Tcase + Rth * Vd * Id 2. This corresponds to the typical biasing condition of +5V, 250 mA at an 85° C case temperature. A minimum MTTF of 1 million hours is achieved for junction temperatures below 247° C. MTTF vs. GND Tab Temperature 1000000 MTTF (million hrs) Parameter 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. 100000 10000 1000 100 50 60 70 80 90 100 Tab Temperature (° C ) Specifications and information are subject to change without notice WJ Communications, Inc • Phone 1-800-WJ1-4401 • FAX: 408-577-6621 • e-mail: [email protected] • Web site: www.wj.com January 2004
