Introduction

The SPF5122Z is a high performance pHEMT MMIC LNA designed for operation from 50MHz to 4000MHz. The on-chip active bias network provides stable current over temperature and process threshold voltage variations. The SPF5122Z offers ultra-low noise figure and high linearity performance in a gain block configuration. Its single-supply operation and integrated matching networks make implementation remarkably simple. A high maximum input power specification make it ideal for high dynamic range receivers.

Features

• Ultra-Low Noise Figure = 0.60 dB at 900MHz
• Gain = 18.9 dB at 900MHz
• High Linearity: IP3 = 40.5 dBm at 1900MHz
• Channel Power = 13.4 dBm (- 65dBc IS95 ACPR, 880MHz)
• P1dB = 23.4 dBm at 1900MHz
• Single-Supply Operation: 5V at IDQ = 90mA
• Flexible Biasing Options: 3 - 5V, Adjustable Current
• Broadband Internal Matching

Applications

• Cellular, PCS, W-CDMA, ISM, WiMAX Receivers
• PA Driver Amplifier
• Low Noise, High Linearity Gain Block Applications
