Description
The DD01-92 directional detector is an integrated directional coupler, Schottky diode combination designed for handset power monitor applications specified from 800 MHz to 2 GHz. It is packaged in the small footprint, SC-88 (6 lead SC-70) package. The DD01-92 incorporates a directional coupler and two GaAs Schottky diodes on a monolithic GaAs chip. By applying forward DC bias to both Schottky diodes, the DD01-92 may be conveniently temperature compensated. The DD01-92 is characterized from 650 MHz to 2.5 GHz and generates a detected signal at 1.8 GHz of approximately 200 mV at 10 mW input power. Each Schottky diode is forward biased to approximately 5 µA by applying 1 V through 100 k resistors as shown in the test circuit.
