- Page 13 Philips Semiconductors +20 dBm single chip linear amplifier for WLAN The last 5 curves are characterization data for supply voltage, temperature and power. The worst-case scenario is the combination of highest temperature/lowest supply. The best-case scenario is the combination of lowest temperature and highest supply voltage. The data has been taken using a non-modulated carrier at 2.5 GHz.
- Page 14 12. APPLICATION WITH THE SA2400A Next diagram is the application of the SA2400A with the SA2411. The interface is simple. Two equal microstrip lines connect the SA2400A with the SA2411. The length of this connection should be kept to a minimum.
