MAX12005RF/IF射频/中频RFID的射频开关规格书PDF中文资料

General Description

The MAX12005 satellite IF switch IC is designed for multi-user applications supporting two quad universal low-noise blocks (LNBs) to be matrix switched to four satellite receivers. The system can be easily expanded to accept 16 satellite IF inputs using the cascade option and one additional satellite IF switch IC. A configuration of eight satellite IF inputs to eight satellite receivers is also possible by using two ICs and adding eight input splitters. The insertion loss of these splitters can be compensated by a +6dB or +12dB input gain select.
