MAXIM MAX2205, MAX2208 Technical data

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 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 termina- tion for interfacing with a directional coupler. The MAX2205 has a high-impedance input to provide a lowloss 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.

DC ELECTRICAL CHARACTERISTICS (MAX2205–MAX2208)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: This device is constructed using a unique set of packaging techniques that imposes a limit on the thermal profile the device

can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry-standard specification, JEDEC 020 rev. C or later, paragraph 7.6, Table 3 for IR/VPR and convection reflow. Preheating is required. Hand or wave soldering is not allowed.

Note 2: Specifications over T

= -40°C to +85°C are guaranteed by design. Production tests are performed at TA= +25°C.

Note 3: Response time is taken from the time the RF signal is applied to 90% of the final value of V

OUT

Note 4: At 800MHz, output voltage is held at a value that nominally results from the final value of +31dBm input power. Deviation from

+31dBm is specified. At 2GHz, output voltage is held at a value that nominally results from +28dBm input power. Deviation from +28dBm is specified.

Note 5: At 2GHz, output voltage is held 22dB lower than specified in Note 4. At 800MHz, output voltage is held 25dB lower than spec-

ified in Note 4.

Note 6: At 800MHz, output voltage is held at a value that nominally results from +15dBm input power. Deviation from +15dBm is

specified. At 2GHz, output voltage is held at a value that nominally results from +13dBm input power. Deviation from +13dBm is specified.

Note 7: For MAX2206, the output voltage is held at 40dB lower input power than specified in Note 6; for MAX2207/MAX2208, output

voltage is held at a value that nominally results from 25dB lower input power than specified in Note 6. Deviation from the nominal input power is specified.
