The TGF2021-08 is designed using TriQuint's proven standard 0.35um power pHEMT production process. The TGF2021-08 typically provides > 39 dBm of saturated output power with power gain of 11 dB. The maximum power added efficiency is 59% which makes the TGF2021-08 appropriate for high efficiency applications. The TGF2021-08 is also ideally suited for Point-to-point Radio, High-reliability space, and Military applications. The TGF2021-08 has a protective surface passivation layer providing environmental robustness.

Combinations of supply voltage, supply current, input power, and output power shall not exceed PD. For a median life time of 1E+6 hrs, Power dissipation is limited to: PD(max) = (150 C - TBASE C) / 10.8 (C/W) Junction operating temperature will directly affect the device median time to failure (TM). For maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels. 4/ TABLE II DC PROBE CHARACTERISTICS (TA = 25 qC, Nominal) Symbol Idss Gm VP VBGS VBGD Parameter Saturated Drain Current Transconductance Pinch-off Voltage Breakdown Voltage Gate-Source Breakdown Voltage Gate-Drain Minimum -1.5 -30 -30 Typical 2400 3000 -1 Maximum -0.5 -14 -14 Unit mA mS V V V Note: For TriQuint's 0.35um power pHEMT devices, RF breakdown >> DC breakdown 2 TriQuint Semiconductor Texas: Phone (972)994-8465 Fax (972)994-8504 Email: Info-mmw@tqs.com Web: www.triquint.com Advance Product Information September 19, 2005 TABLE III RF CHARACTERIZATION TABLE 1/ (T A = 25 C, Nominal) Vd = 10V Idq = 600mA TGF2021-08 Vd = 12V Idq = 600mA SYMBOL Power Tuned: Psat PAE Gain Rp 2/ Cp 2/ L 3/, 4/ Efficiency Tuned: Psat PAE Gain Rp 2/ Cp 2/ L 3/, 4/ PARAMETER UNITS Saturated Output Power Power Added Efficiency Power Gain Parallel Resistance Parallel Capacitance Load Reflection coefficient 39.8 50 11 3.33 3.705 0.920 176.3 40.5 48 11 3.99 3.811 0.920 175.4 dBm % dB pF - Saturated Output Power Power Added Efficiency Power Gain Parallel Resistance Parallel Capacitance Load Reflection coefficient 39 59 11.5 6.13 4.308 0.937 173.8 39.7 55 11 6.95 4.042 0.935 173.2 dBm % dB pF - 1/ Values in this table are scaled from measurements taken from a 1mm unit pHEMT cell at 10 GHz 2/ Large signal equivalent pHEMT output network 3/ Optimum load impedance for maximum power or maximum PAE at 10 GHz 4 The reflection coefficients for this device have been calculated from the scaled large signal Rp & Cp.

Do not use flux Coefficient of thermal expansion matching is critical for long-term reliability. Devices must be stored in a dry nitrogen atmosphere. Component placement and adhesive attachment assembly notes: * * * * * * * Vacuum pencils and/or vacuum collets are the preferred method of pick up. Air bridges must be avoided during placement. The force impact is critical during auto placement. Organic attachment can be used in low-power applications. Curing should be done in a convection oven; proper exhaust is a safety concern. Microwave or radiant curing should not be used because of differential heating. Coefficient of thermal expansion matching is critical. Interconnect process assembly notes: * * * * * Thermosonic ball bonding is the preferred interconnect technique. Force, time, and ultrasonics are critical parameters. Aluminum wire should not be used. Devices with small pad sizes should be bonded with 0.0007-inch wire. Maximum stage temperature is 200 C.
