آر اف (فرکانس رادیویی) و بی‌سیم تقویت‌کننده‌ آر اف

Product Attributes

Features

• Low-voltage, three-stage linear PA optimized for 802.11b/g WLAN applications in the 2.4GHz ISM band
• Integrated adjustable bias control, power detector, and shutdown mode
• 29dB power gain with up to +24dBm linear output power at 24% efficiency from a single +3.3V supply
• First sidelobe suppression <-32dBc and second sidelobe suppression <-55dBc under 802.11b modulation
• Matchable across output power levels from +10dBm to +24dBm for optimum efficiency and performance
• High +28dBm saturated output power meeting 802.11g OFDM modulation requirements
• External bias control pin for dynamic adjustment of device supply current at lower output power levels, improving efficiency while maintaining adequate sidelobe suppression
• Proprietary internal bias circuitry for stable device performance over temperature and supply voltage variations
• Logic-level shutdown pin reducing supply current to 0.5μA without external power switches; integrated shutdown function ensures controlled turn-on and turn-off timing
• Integrated power detector with 20dB dynamic range and ±0.8dB accuracy at maximum output power level, providing a buffered DC voltage proportional to device output power — saving cost and board space
• 3×4 UCSP package measuring only 1.5mm×2mm
