7 / 9 page Specifications and information are subject to change without notice WJ Communications, Inc • Phone 1-800-WJ1-4401 • FAX: 408-577-6621 • e-mail: sales@wj.com • Web site: www.wj.com September 2004 The Communications Edge TM AH31 High Dynamic Range IF Amplifier Product Information Reference Design: 870 – 960 MHz Typical Performance Frequency 900 MHz S21 16.8 dB S11 -14 dB S22 -11 dB Output P1dB +21 dBm Output IP3 +41 dBm Noise Figure 2.1 dB Bias 5 V @ 150 mA Notes: 1. The amplifier should be connected directly to a +5 V regulator; no dropping resistor is required. 2. If no DC signal is present at the input (pin 1), C1 can be removed. The gate is internally grounded in the amplifier. 3. All components are of size 0603. 4. This is a reference design only. Sample evaluation boards are not readily available for this circuit. The actual implementation can be achieved by requesting an AH31 Evaluation board (any frequency) and replacing the passive components with the values given above.
