| Filtronic Solid State FEATURES LP1500SOT223 Low Noise, High Linearity Packaged PHEMT * * * * * +27 dBm Typical Power at 1800 MHz 15 dB Typical Power Gain at 1800 MHz 1.0 dB Typical Noise Figure +42 dBm Typical Intercept Point Color-coded by IDSS range GATE SOURCE SOURCE DRAIN (TOP VIEW) DESCRIPTION AND APPLICATIONS The LP1500SOT223 is a packaged Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam direct-write 0.25 m by 1500 m Schottky barrier gate. The recessed "mushroom" gate structure minimizes parasitic gate-source and gate resistances. The epitaxial structure and processing have been optimized for reliable high-power applications. The LP1500 also features Si3N4 passivation and is available in a die form or in a flanged ceramic package (P100) for high-power applications, or in the SOT-89 plastic package. Typical applications include PCS/Cellular low-voltage high-efficiency output amplifiers, and general purpose power amplifiers. The LP 1500 may be procured in a variety of grades, depending upon specific user requirements. Standard lot screening is patterned after MIL-STD-19500, JANC grade.

Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device. 2. Recommended Continuous Operating Limits should be observed for reliable device operation. 3. Power Dissipation defined as: PT (PDC + PIN) - POUT, where: PDC = DC bias power, POUT = RF output power, and PIN = RF input power. Provide for adequate heatsinking at the large source lead. 4. Power Dissipation to be de-rated as follows above 25C: Absolute Maximum: PT = 1.7W - (10mW/C) x THS Recommended Continuous Operating: PT = 1.4W - (10mW/C) x THS where THS = heatsink or ambient temperature. 5. Specifications subject to change without notice. HANDLING PRECAUTIONS: Care should be exercised during handling to avoid damage to the devices. Proper Electrostatic Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and testing. These devices should be treated as Class 1A (0-500V), and further information on ESD control measures can be found in MIL-STD-1686 and MILHDBK-263. APPLICATIONS NOTES AND DESIGN DATA: Applications Notes are available from your local FSS Sales Representative, or directly from the factory. Complete design data, including S-parameters, Noise data, and Large-Signal models, is available on 3.5" diskette, or may be down-loaded from our Web Page.
