Product Description
Sirenza Microdevices' SHF-0189 is a high performance AlGaAs/ GaAs Heterostructure FET (HFET) housed in a low-cost surface-mount plastic package. The HFET technology improves breakdown voltage while minimizing Schottky leakage current resulting in higher PAE and improved linearity. Output power at 1dB compression for the SHF-0189 is +27 dBm when biased for Class AB operation at 8V,100mA. The +40 dBm third order intercept makes it ideal for high dynamic range, high intercept point requirements. It is well suited for use in both analog and digital wireless communication infrastructure and subscriber equipment including 3G, cellular, PCS, fixed wireless, and pager systems.

[1] 100% tested - Insertion gain tested using a 50 ohm contact board (no matching circuitry) during final production test. [2] Sample tested - Samples pulled from each wafer/package lot. Sample test specifications are based on statistical data from sample test measurements. The test fixture is an engineering application circuit board. The application circuit was designed for the optimum combination of linearity, P1dB, and VSWR. [3] Maximum recommended power dissipation is specified to maintain TJ<150C at TL=85C. VDS * IDQ<0.8W is recommended for continuous reliable operation.

SHF-0189 0.5 Watt HFET Absolute Maximum Ratings
MTTF is inversely proportional to the device junction temperature. For junction temperature and MTTF considerations the bias condition should also satisfy the following expression: PDC < (TJ - TL) / RTH where: PDC = IDS * VDS (W) TJ = Junction Temperature (C) TL = Lead Temperature (pin 4) (C) RTH = Thermal Resistance (C/W)
MTTF @ TJ=150C exceeds 1E7 hours

Description
Connection to ground. Use via holes to reduce lead inductance. Place vias as close to ground leads as possible. RF Output Same as Pin 2
Part Symbolization The part will be symbolized with the "H1" designator and a dot signifying pin 1 on the top surface of the package.
Mounting and Thermal Considerations It is very important that adequate heat sinking be provided to minimize the device junction temperature. The following items should be implemented to maximize MTTF and RF performance. 1. Multiple solder-filled vias are required directly below the ground tab (pin 4). [CRITICAL] 2. Incorporate a large ground pad area with multiple plated-through vias around pin 4 of the device. [CRITICAL] 3. Use two point board seating to lower the thermal resistance between the PCB and mounting plate. Place machine screws as close to the ground tab (pin 4) as possible. [RECOMMENDED] 4. Use 2 ounce copper to improve the PCB's heat spreading capability. [RECOMMENDED]
