آر اف (فرکانس رادیویی) و بی‌سیم آشکارساز آر اف

Product Attributes

Features

• Wide bandwidth (800MHz to 2GHz)
• Suitable for GSM/EDGE (MAX2206), TDMA (MAX2207), and CDMA (MAX2205/MAX2208) applications
• Accepts RF signal input from directional coupler; outputs highly repeatable voltage that increases monotonically with input power
• Output compensated for temperature and process variations; worst-case variation <±1dB at full power, <±2.5dB at minimum power
• MAX2206: 40dB dynamic range for GSM/EDGE applications
• MAX2207: reduced current consumption for TDMA applications
• MAX2205/MAX2208: integrated filter for average power detection of CDMA signals over 25dB dynamic range
• MAX2206/MAX2207/MAX2208: internal 50Ω termination for directional coupler interface
• MAX2205: high-impedance input for low-loss resistive tap in CDMA applications
• All devices allow external user control of averaging time constant
• Space-saving 2×2, 0.5mm pitch UCSP package; only three external components required
• 2×2 UCSP occupies only 1mm²
• Internal temperature compensation provides ±0.3dB detection accuracy
• No external filter or op-amp required
• Power detection range: 40dB (MAX2206), 25dB (MAX2205/MAX2207/2208)

Applications

• Dual-band GSM/EDGE handsets
• Dual-band CDMA/TDMA handsets
