GigOptix launches single-bias broadband power amplifiers

GigOptix Inc of Palo Alto, CA, USA, which designs optical modulators, drivers and transimpedance amplifier (TIA) ICs based on III-V materials, has extended its range of broadband amplifiers with the release of two new monolithic microwave integrated circuits (MMICs).

The iT2003 and iT2004 power amplifiers both offer an operating range of 2-20GHz and are designed for use in military and defense applications such as microwave amplifier assemblies.

Both are highly efficient broadband GaAs MMIC traveling-wave amplifiers with single-bias operation, which significantly eases design challenges by removing the need for a complex biasing network to manage the bias sequencing, says the firm. The iT2004 is designed for high-output-power applications, while the iT2003 supports medium-output-power applications.

The iT2004 provides a saturated output power of 29dBm up to 7GHz and greater than 26dBm up to 20GHz. Average gain of 10dB with flatness of ±1dB is provided up to 20GHz. DC power consumption is as low as 3W and the input/output ports are AC coupled.

The iT2003 provides a saturated output power close to 27dBm up to 8GHz and greater than 25dBm up to 16GHz. Average gain is 15dB. DC power consumption is as low as 1.76W and the input/output ports are AC coupled.

“The launch of these two new products is just the first step GigOptix is taking to revitalize and strengthen our RF portfolio and to re-engage with customers in the RF field,” says chief technology officer Andrea Betti-Berutto. “The iT2003 and iT2004 are following our RF products 'best in class' tradition by offering the best power efficiency of any single-bias broadband amplifier in the market,” he claims.

Engineering samples of iT2003 and iT2004 die are available along with a test fixture. Packaged versions will be developed later this year.
