Triband passive signal receptor network

A surface acoustic wave (SAW) triplexer comprising:

• an input terminal providing an incoming signal;
• a low pass filter network connected to the input terminal for reception and separation of the incoming signal of a low frequency band having signal components within a frequency band of 824 MHz to 894 MHz;
• a high pass filter network connected to the input terminal for reception and separation of the incoming signal of a high frequency band with signal components within a frequency band of 1850 to 1990 MHz;
• and
• a surface acoustic wave (SAW) filter which connected to the input terminal for reception and separation of the incoming signal at a frequency band with signal components within 1570 to 1580 MHz, wherein the SAW filter comprises a transducer and reflector fabricated on a piezoelectric substrate for providing a low insertion loss bandpass filter.

A triplexer comprising:

• an input terminal for providing an incoming signal;
• a low pass filter network connected to the input terminal for receiving and separating the incoming signal into a low frequency band;
• a high pass filter network connected to the input terminal for receiving and separating the incoming signal into a high frequency band;
• and
• a surface acoustic wave (SAW) filter connected to the input terminal for receiving and separating the incoming signal at a frequency band located between the low and the high frequency bands.
