آر اف (فرکانس رادیویی) و بی‌سیم سایر آی سی‌ و ماژول‌های آر اف

Product Attributes

Features

• High-performance SiGe receiver front-end IC achieving low noise and high linearity at low supply current
• Integrates multiple unique features including LO frequency multiplier and divider, dual LNA gain settings, and low-current paging mode for extended handset standby time
• Contains six ICs: four operating at cellular and PCS frequencies, one at cellular frequency only, and one at PCS frequency only
• High input IIP3 on each device's LNA minimizes intermodulation and harmonics in the presence of large interfering signals
• In low-gain mode, LNA bypass provides higher cascaded IIP3 at reduced current
• Low-current, high-gain paging mode available
• CDMA mixers for cellular and PCS bands feature high linearity, low noise, and differential IF output
• FM mixer designed for low current and single-ended output
• All devices in 20-pin TSSOP-EP package with exposed pad (EP), rated for extended temperature range (-40°C to +85°C)
• Ultra-high linearity at ultra-low current and noise
• +2.78 to +3.68V operating voltage
• Pin-selectable low-gain mode reduces gain by 17dB and current by 3mA
• Pin-selectable paging mode reduces current consumption by 6mA when transmitter is inactive
• LO output buffer
• LO frequency multiplier (MAX2321)
• LO frequency divider (MAX2326)
• 0.1μA shutdown current
• 20-pin TSSOP-EP package

Applications

• CDMA/TDMA/PDC/WCDMA/GSM cellular phones
• Single/dual/tri-mode phones
• Wireless Local Loop (WLL)
