It is an upconverter with RF output frequencies of 17 to 27 GHz. It contains a frequency doubler and local oscillator (LO) amplifier, operating at LO Input frequencies of 8 - 13 GHz. The part is designed using TriQuint's 0.25 um 3MI power pHEMT process. The TGC4405 nominally provides 13 dB Conversion Gain and 28 dBm OTOI when operated with LO inputs from 2 - 5 dBm. The part also achieves 30 dBc typical isolation between the fundamental and doubled frequency. The TGC4405 is ideally suited for low cost markets such as Point-to-Point Radio, and Ku-band Satellite Communications. The TGC4405 is 100% DC and RF tested on-wafer to ensure performance compliance. The TGC4405 has a protective surface passivation layer providing environmental robustness.

Vacuum pencils and/or vacuum collets are the preferred method of pick up. 2. Air bridges must be avoided during placement. 3. The force impact is critical during auto placement. 4. Organic attachment (i.e. epoxy) can be used in low-power applications. 5. Curing should be done in a convection oven; proper exhaust is a safety concern. Reflow process assembly notes: 1. Use AuSn (80/20) solder and limit exposure to temperatures above 300C to 3-4 minutes, maximum. 2. An alloy station or conveyor furnace with reducing atmosphere should be used. 3. Do not use any kind of flux. 4. Coefficient of thermal expansion matching is critical for long-term reliability. 5. Devices must be stored in a dry nitrogen atmosphere. Interconnect process assembly notes: 1. Thermosonic ball bonding is the preferred interconnect technique. 2. Force, time, and ultrasonics are critical parameters. 3. Aluminum wire should not be used. 4. Devices with small pad sizes should be bonded with 0.0007-inch wire.
