ADET-5000
RF Power Detector
Data Sheet
Description
ADET-5000 is a wide bandwidth, wide dynamic range
temperature-compensated diode power detector for
operation from 700 MHz to 2.6 GHz. Its high sensitivity
and wide bandwidth support fast inner-loop calibration
and true envelope sampling of modulated signals for
accurate power leveling of modulated waveforms for use
in cellular handsets and data cards.
ADET-5000 features circuit technology that is aligned
optimally to work with transceivers requiring external
detection for inner-loop power control. Superb tem-
perature and voltage compensation maintains inner-
loop accuracy over extreme operating conditions. In
power-down mode, ADET-5000 presents high output
impedance to the transceiver, minimizing loading of any
other detectors connected to the transceiver detector
input line. This characteristic allows the customer to utilize
ADET-5000 to daisy-chain numerous power amplifier
couplers together with a single detector.
ADET-5000’s nominal input impedance is 100 ohms,
allowing the sensitivity and detection range to be
trimmed externally with a shunt input resistor. This allows
user-adjustability of effective coupling ratios to maximize
dynamic range and to compensate variable output
power targets and daisy-chain configurations. ADET-5000
is manufactured on an advanced InGaP HBT (hetero-
junction Bipolar Transistor) MMIC (microwave monolithic
integrated circuit) technology offering state-of-the-art
reliability, temperature stability and ruggedness
