Analog Devices Inc./Maxim Integrated MAX2208EBS+T10

Overview

MAX2208EBS+T10 from Maxim Integrated is a CDMA-optimized RF power detector IC operating from 800MHz to 2GHz, delivering 25dB dynamic range with ±1.3dB temperature-induced variation at low input power and ±0.3dB detection accuracy via internal compensation. It features integrated filtering for average power detection in CDMA PA modules and interfaces directly with directional couplers using internal 50Ω termination.

For engineers reviewing the MAX2208EBS+T10 datasheet, MAX2208EBS+T10 pinout, MAX2208EBS+T10 application, or MAX2208EBS+T10 equivalent, key selection criteria include its 2×2 UCSP package footprint, shutdown logic compatibility, 15µs response time at +25°C, and suitability for WCDMA handset transmit power control loops requiring stable analog output voltage vs. RF input power.

Technical Context

The MAX2208EBS+T10 implements a temperature-compensated peak-detection architecture optimized for CDMA signal envelope tracking. Its internal 50Ω RF input termination enables direct coupling from directional couplers without external matching networks, while the SHDN pin provides TTL-compatible logic control of detector operation.

It delivers monotonic DC output voltage proportional to logarithmic RF input power across 800MHz–2GHz, with specified performance at both 800MHz (+15dBm nominal reference) and 2GHz (+13dBm nominal reference). The device operates from 2.7V to 5.0V supply and maintains ±2.5dB worst-case variation over full temperature range at minimum detectable power.

FAQ

What is the primary RF frequency range supported by the MAX2208EBS+T10?

The MAX2208EBS+T10 operates from 800MHz to 2GHz, covering all major CDMA and WCDMA bands including PCS (1850–1910MHz) and AWS (1710–1755MHz/2110–2155MHz). Its performance is characterized at both 800MHz (+15dBm nominal reference) and 2GHz (+13dBm nominal reference), ensuring reliable detection across dual-band handset architectures. The MAX2208EBS+T10 maintains specified accuracy within this range under all operating conditions.

Does the MAX2208EBS+T10 require external filtering for CDMA signal detection?

No, the MAX2208EBS+T10 integrates an internal filter optimized for CDMA average power detection across its 25dB dynamic range. This eliminates the need for external RC networks or op-amp-based filtering stages commonly required with generic log detectors. The MAX2208EBS+T10 achieves this while maintaining compatibility with standard directional couplers via its internal 50Ω RF termination.

How does the shutdown functionality work on the MAX2208EBS+T10?

The MAX2208EBS+T10 uses the RFIN/SHDN pin (A1) for combined RF input and logic control: driving this pin below 0.6V places the device in shutdown mode with supply current reduced to 0.5–10µA, while pulling it above 2.0V enables normal operation. This dual-function pin simplifies PCB routing and reduces component count compared to dedicated enable pins. The MAX2208EBS+T10 retains full pin compatibility with other members of the MAX2205–MAX2208 family.

What package type and dimensions does the MAX2208EBS+T10 use?

The MAX2208EBS+T10 is packaged in a 2×2 mm, 0.5mm-pitch UCSP (Ultra Compact Silicon Package) with four solder bumps. Its total footprint measures exactly 1.01mm × 1.01mm, occupying only 1mm² of PCB area. This lead-free package is designed for reflow soldering per JEDEC J-STD-020C and requires no wave or hand soldering. The MAX2208EBS+T10 shares this exact package with MAX2205EBS+, MAX2206EBS+, and MAX2207EBS+.

Can the MAX2208EBS+T10 be used in GSM/EDGE applications?

Yes, the MAX2208EBS+T10 is pin-compatible and functionally suitable for GSM/EDGE applications despite being optimized for CDMA. Its 800MHz–2GHz range, 25dB dynamic range, and 15µs response time meet core requirements for dual-mode handset designs. While the MAX2206EBS+T10 offers 40dB dynamic range specifically for GSM/EDGE, the MAX2208EBS+T10 enables shared PCB layouts and calibration firmware across multimode platforms due to identical pinout and supply specifications.
