Hittite Microwave Corp. announced five GaAs PHEMT 1W and 2W monolithic microwave IC (MMIC) power amplifiers that cover the 6- to 13GHz range for point-to-point and point-to-multi-point radios, test instrumentation, military and space applications.

The five new GaAs PHEMT MMICHMC590, HMC590LP5(E), HMC591, HMC591LP5(E), and HMC592all have RF I/Os that are DC blocked and matched to 50 ohms.

High gain, output power
Optimized for high gain and high output power, the HMC590 and HMC590LP5(E) 1W power amplifiers operate from 6GHz to 9.5GHz. According to Hittite, these amplifiers provide 25dB of gain, +31.5dBm of saturated output power, typical output IP3 of +40dB and 25 percent PAE from a +7V supply. The HMC590 is intended for multichip modules (MCMs) and hybrid assemblies, while the HMC590LP5(E) is suitable for SMT applications.

The HMC591 and HMC591LP5(E) 2W power amplifiers exhibit high efficiency and high output IP3 characteristics over the 6- to 10GHz operating range, the company said. These amplifiers provide 23.5 dB of gain, +34dBm of saturated power, typical output IP3 of +43 dBm and 27 percent PAE from a +7V supply. HMC591 also targets MCMs and hybrid assemblies, while the HMC591LP5(E) suits SMT applications.

Lastly, HMC592 is a 1W power amplifier operating from 10- to 13GHz. This amplifier die provides 20dB of gain, +30.5dBm of saturated power, and 23 percent PAE from a +7V supply. The HMC592 is suitable for integration into MCMs and exhibits a typical output IP3 of +38dBm, Hittite said.

Packaging options
The HMC590, HMC591 and HMC592 are furnished in chip form, while the HMC590LP5(E) and HMC591LP5(E) are housed in 5-by-5mm RoHS-compliant packages.

Die product samples, SMT-packaged samples, and evaluation PC boards for all SMT-packaged products are available from stock and can be ordered via the company's e-commerce site or via direct purchase order.
