LPA6836V

Preliminary Data Sheet • FEATURES ♦ 25 dBm Output Power at 1-dB Compression at 18 GHz ♦ 9.5 dB Power Gain at 18 GHz ♦ 55% Power-Added Efficiency ♦ Source Vias to Backside Metallization DRAIN BOND PAD LPA6836V MEDIUM POWER PHEMT WITH SOURCE VIAS GATE BOND PAD • DESCRIPTION AND APPLICATIONS DIE SIZE: 15.4X14.2 mils (390x360 µm) DIE THICKNESS: 3.9 mils (100 µm) BONDING PADS: 3.0X3.0 mils (75x75 µm) The FPA6836V is an Aluminum Gallium Arsenide / Indium Gallium Arsenide (AlGaAs/InGaAs) Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing an Electron-Beam directwrite 0.25 µm by 360 µm Schottky barrier gate. The recessed “mushroom” gate structure minimizes parasitic gate-source and gate resistances. The epitaxial structure and processing have been optimized for high dynamic range. Typical applications include high dynamic range driver stages for commercial applications including wireless infrastructure systems, broad bandwidth amplifiers, and optical systems. Source vias have been added for improved performance and assembly convenience. Each via hole has 0.02 nH of inductance. Additionally, the via holes remove the need for source bond wires, meaning only two bond wires are required for assembly. Because the via connects the source pad to the backside metallization, self-bias configurations should be designed with caution. • ELECTRICAL SPECIFICATIONS @ TAmbient = 25°C Parameter Saturated Drain-Source Current Power at 1-dB Compression Power Gain at 1-dB Compression Power-Added Efficiency Maximum Drain-Source Current Transconductance Gate-Source Leakage Current Pinch-Off Voltage Gate-Source Breakdown Voltage Magnitude Gate-Drain Breakdown Voltage Magnitude Thermal Resistivity frequency=18 GHz Phone: (408) 988-1845 Fax: (408) 970-9950 http:// www.filss.com Revised: 2/22/02 Email: sales@filss.com Symbol IDSS P-1dB G-1dB PAE IMAX GM IGSO VP |VBDGS| |VBDGD| ΘJC Test Conditions VDS = 2 V; VGS = 0 V VDS = 8 V; IDS = 50% IDSS VDS = 8 V; IDS = 50% IDSS VDS = 8 V; IDS = 50% IDSS VDS = 2 V; VGS = 1 V VDS = 2 V; VGS = 0 V VGS = -5 V VDS = 2 V; IDS = 2 mA IGS = 2 mA IGD = 2 mA Min 80 24 8.5 Typ 115 25 9.5 55 190 Max 125 Units mA dBm dB % mA mS 75 -0.25 11 12 100 1 -1.2 15 16 100 10 -2.0 µA V V V °C/W Preliminary Data Sheet • ABSOLUTE MAXIMUM RATINGS Parameter Drain-Source Voltage Gate-Source Voltage Drain-Source Current Gate Current RF Input Power Channel Operating Temperature Storage Temperature Total Power Dissipation Notes: • • Symbol VDS VGS IDS IG PIN TCH TSTG PTOT Test Conditions TAmbient = 22 ± 3 °C TAmbient = 22 ± 3 °C TAmbient = 22 ± 3 °C TAmbient = 22 ± 3 °C TAmbient = 22 ± 3 °C TAmbient = 22 ± 3 °C — TAmbient = 22 ± 3 °C LPA6836V MEDIUM POWER PHEMT WITH SOURCE VIAS Min Max 10 -4 2xIDSS 18 180 175 Units V V mA mA mW ºC ºC W -65 175 1.4 • Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device.

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 (0-500 V). Further information on ESD control measures can be found in MIL-STD-1686 and MIL-HDBK-263. ASSEMBLY INSTRUCTIONS The recommended die attach is gold/tin eutectic solder under a nitrogen atmosphere. Stage temperature should be 280-290°C; maximum time at temperature is one minute. The recommended wire bond method is thermo-compression wedge bonding with 0.7 or 1.0 mil (0.018 or 0.025 mm) gold wire. Stage temperature should be 250-260°C.
