LT5500数据手册RF/IF射频/中频RFID的射频接收器规格书PDF

描述 Description

The LT®5500 is a receiver front end IC designed for low voltage operation and is compatible with the LTC family of WLAN products. The chip contains a low noise amplifier (LNA), a Mixer and an LO buffer. The IC is designed to operate over a power supply voltage range from 1.8V to 5.25V.The LNA can be set to either high gain or low gain mode. At 2.5GHz, the high gain mode provides 13.5dB gain and a noise figure (NF) of 4dB. The LNA in low gain mode provides –14dB gain and an IIP3 of +8dBm at 2.5GHz.
The mixer has 5dB of conversion gain and an IIP3 of –2.5dBm at 2.5GHz, with –10dBm LO input power.
