MAX2205, MAX2206, MAX2207, MAX2208
RF Power Detectors in UCSP
The Industry's Smallest Power Detection Circuit
|
Status
Active: In Production.
Description
The MAX2205–MAX2208 wideband (800MHz to 2GHz)
power detectors are ideal for GSM/EDGE (MAX2206),
TDMA (MAX2207), and CDMA (MAX2205/MAX2208)
applications. The MAX2206/MAX2207/MAX2208 take an
RF signal from a directional coupler at the input, and output
a highly repeatable voltage. The output voltage
increases monotonically with increasing input power. The
output is compensated for temperature and process
shifts, reducing the worst-case variation to less than
±1dB at full power and ±2.5dB at the lowest power.
The MAX2206 features 40dB dynamic range, making
it ideally suited to GSM/EDGE applications. The
MAX2207 offers reduced current consumption for TDMA
applications. The MAX2205/MAX2208 each have an integrated
filter to allow for average power detection of
CDMA signals over a 25dB dynamic range. The MAX2206/MAX2207/MAX2208 offer internal 50Ω termination
for interfacing with a directional coupler. The
MAX2205 has a high-impedance input to provide a low-loss
resistive tap in CDMA applications. All devices allow
the user to control the averaging time constant externally.
The MAX2205–MAX2208 come in a space-saving 2 x 2,
0.5mm-pitch UCSP™ and require only three external
components.
