AH202 1W High Linearity Amplifier Product Features Product Description Functional Diagram The AH202 is a 1-Watt driver amplifier that offers excellent dynamic range in a low-cost, lead-free/RoHScompliant 6x6 mm 28-pin QFN surface-mount package. This device provides its optimum P1dB and OIP3 performance when biased at + 11 V; It can also be biased as low as +9 V for lower power applications. • 50 – 2200 MHz • +30 dBm P1dB • +47 dBm Output IP3 • 17 dB Gain @ 900 MHz 28 • Internally Matched • Lead-free/RoHS-compliant 6x6mm QFN SMT package Applications • Mobile Infrastructure • CATV / DBS • Optimal for VHF / UHF broadband applications • Defense / Homeland Security The backside metalization provides excellent thermal dissipation while allowing visible evidence of solder reflow across the bottom of the package on a SMT board. Superior thermal design allows the product an MTTF of over 100 years at a mounting temperature of +85º C. All devices are 100% RF & DC tested.

The amplifier can be operated at 105 °C case temperature for up to 1000 hours over its lifetime with minimal 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 hottest part of the junction to the backside copper paddle. 3. This corresponds to the typical biasing condition of +11V, 350 mA at an 85° C case temperature. A minimum MTTF of 1 million hours is achieved for junction temperatures below 160° C.
