United Monolithic Semiconductors’ CHE1260-QAG is a bidirectional detector monolithic microwave IC (MMIC) that integrates a passive bidirectional coupler, two matched detector diodes, and two reference diodes. It allows for the measurement of transmitted and reflected power over a wide frequency range of 10 to 27 GHz. It has 30 dB of dynamic range, and is ESD protected.
The detector is designed for a wide range of applications where an accurate transmitted power control is required, typically in commercial communication systems. The circuit is manufactured with a Schottky diode MMIC process, 1 µm gate length, via holes through the substrate, and air bridges, and is supplied in a leadless 16L-QFN3x3 SMD package.
