The DD02-999LF directional detector is an alternative to the DD01-999 with improved insertion loss and directivity with slightly lower sensitivity. It is designed for handset power monitor applications from 800 MHz to 3 GHz. It is packaged in the small footprint, SC-88 (6 lead SC-70) package. The DD02-999LF incorporates a directional coupler and two GaAs Schottky diodes on a monolithic GaAs chip. By applying forward DC bias to both Schottky diodes, the DD02-999LF may be conveniently temperature compensated. The DD02-999LF is characterized from 500 MHz to 3 GHz and generates a detected signal at 1.8 GHz of approximately 190 mV at 10 mW input power. Each Schottky diode is forward biased to approximately 5 μA.
