RF Power Detectors in UCSP
General 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 out-
put 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 inte-
grated filter to allow for average power detection of
CDMA signals over a 25dB dynamic range. The
MAX2206/MAX2207/MAX2208 offer internal 50Ω termina-
tion 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 ✕ 2,
0.5mm-pitch UCSP™ and require only three external
components.
