The TriQuint TGA4905-CP is a compact 4 Watt High Power Amplifier Packaged MMIC for Ka-band applications. The part is designed using TriQuint's proven standard 0.25 um gate Power pHEMT production process.
The TGA4905 provides a nominal 36 dBm of output power at an input power level of 18 dBm from 25-31 GHz with a small signal gain of 22 dB.
The part is ideally suited for low cost emerging markets such as base station transmitters for satellite ground terminals, point to point radio and LMDS.
The TGA4905-CP is 100% RF tested to ensure performance compliance.

TGA4953-SL General Description
The TriQuint TGA4953-SL is part of a series of surface mount modulator drivers suitable for a variety of driver applications and is compatible with Metro MSA standards.
The TGA4953-SL consists of two high performance wideband amplifiers combined with off chip circuitry assembled in a surface mount package. A single TGA4953-SL placed between the MUX and Optical Modulator provides OEMs with a board level modulator driver surface mount solution.
The TGA4953-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation (1.1W at Vo = 6V), very low rail ripple, high voltage drive capability at 5V bias (6 V amplitude adjustable to 3 V), low output jitter (1ps rms typical), and low input drive sensitivity (250mV at Vo = 6V).
The TGA4953-SL requires external DC blocks, a low frequency choke, and control circuitry.
The TGA4953-SL is available on an evaluation board.
RoHS compliant version available.

1/ These ratings represent the maximum operable values for this device 2/ Combinations of supply voltage, supply current, input power, and output power shall not exceed PD at a package base temperature of 80°C 3/ When operated at this bias condition with a baseplate temperature of 80°C, the MTTF is reduced 4/ Junction operating temperature will directly affect the device median time to failure (MTTF). For maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels. 5/ Assure VCTRL1 never exceeds VD1, and VCTRL2 never exceeds VD2T during bias up and down sequences.
