HITTITE Microwave Corporation, represented by ASD Technology in Australia and New Zealand, has announced the introduction of four new InGaP HBT MMIC power amplifiers for applications in cellular/PCS/3G and fixed wireless from 400 to 2200MHz.
The HMC450QS16G is an 800-1000MHz power amplifier offering 26dB of gain, +40dBm OIP3 and +28.5dBm of saturated output power and is ideal as a linear driver in BTS and repeater applications.
HMC450QS16G operates from a single +5.0V supply, and offers the same pinout and functionality as Hittite's higher band HMC413QS16G 1.6-2.3GHz PA.
The HMC457QS16G is a 1.7-2.3GHz power amplifier delivering 26dB gain from 1.7 to 2.0GHz and 25dB gain from 2.0 to 2.2GHz. Output IP3 performance can be optimised to +45dBm at 1.9 and 2.1GHz utilising a minimum number of external components.
Both the HMC450QS16G and the HMC457QS16G are packaged in a miniature 16 lead QSOP plastic package, and offer an integrated power control (Vpd) pin which can be used for full power down or RF output power/current control.
Also new are the HMC452ST89 and the HMC453ST89 high dynamic range power amplifiers offering 1.0W and 1.6W of saturated output power respectively.
Both amplifiers are packaged in a low cost industry standard SOT89 package, and operate from a single +5V supply.
With a minimum of external components, the output IP3 can be optimised to +50dBm from 1.8-2.2GHz. High output IP3 and PAE make both the HMC452ST89 and HMC453ST89 suitable drivers and power amplifiers for infrastructure applications.
Samples and evaluation PC boards are available from stock and can be ordered on line. Released data sheets are available on-line at www.hittite.com.
