2-Way 90° hybrid coupler - The QH9056 is a 4-port, hybrid coupler covering the full 30 to 520 MHz band. This stripline unit is designed for amplifiers and radios in the VHF/UHF band. Conservatively rated at 400 W CW, this unit eliminates ferrites and will withstand severe input unbalances. Low profile, fully bonded, and highly repeatable.
RFMD’s new RFSA2644/2654 6-bit digital step attenuators (DSAs) feature high linearity over their entire 31.5 dB gain control range with excellent step accuracy in 0.5 dB steps. They are programmed via a serial mode control interface that is both 3 and 5 V compatible.
Linear Technology Corporation introduces the LTC2996 high accuracy temperature sensor for 2.25 to 5.5 V systems. The LTC2996 measures a remote diode’s temperature with ±1° C accuracy and its own die temperature with ±2° C accuracy while rejecting errors due to noise and series resistance.
