The DD02-999 directional detector is an alternative to theDD01-999 with improved insertion loss and directivity with slightly lower sensitivity.It is designed for handset power monitor applica- tions from 800 MHz to 3 GHz.It is packaged in the small footprint,SC-88 (6 lead SC-70) package.The DD02-999 incorporates adirectional coupler and two GaAs Schottky diodes on a monolithic GaAs chip.By applying forward DC bias to both Schottky diodes,the DD02-999 may be conveniently temperature compensated.
The DD02-999 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 A.
