Description
The DD02-999 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 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 a
directional 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 µA.
