Since the Audiohouse bid a•repeater which was not 100% <br />.solid state, we therefore must consider them to be.non-complaint. <br />Themajor area of concern between RCA, General Electric and <br />Motorola is in the area of the repeater duplexer requirements. The <br />specification was stated as "proper duplexers and band pass filters <br />_t..;.. must be supplied...", which leaves it to the discretion of the <br />'Vendor -to define "proper". The following table lists the duplexers <br />bid, by company, and the associated losses injected into the system <br />by each type duplexer. <br />• Co --many - D�lplexer 'Filter <br />RCA <br />General Electric <br />Motorola <br />DB 4032 and DB 4041H1 <br />Sinclair R103G <br />Not specified <br />IR <br />Tnsertiori Loss <br />S dB -Rx; 3 dB -Tx <br />1.6 dB Rx• & Tx <br />Unknown <br />'JUL 2 0 1977 BOOK <br />P <br />l 1 <br />6 <br />30 PACE 242 <br />
