Gary, That is a Motorola part number, and is equivalent to the TLE9022, which is the same as a Celwave PD526-4-2. This is a current-model unit which is also sold for use with the Quantar and MTR2000 UHF stations. It is specified for 1.3 dB maximum insertion loss and 120 dB minimum isolation, when tuned per the instructions. Curiously, the tuning procedure specifies a Boonton 92E RF Millivoltmeter and an HP8656B Signal Generator; you'd think a vector network analyzer would be specified. I have one of these duplexers in service now, and it performs as expected.
I have the tuning instructions in PDF somewhere, and I'll e-mail you a copy. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Gary Sent: Sunday, December 02, 2007 5:00 PM To: [email protected] Subject: [Repeater-Builder] Celwave UHF 6 cavity Rack mounted Duplexer Hello Group. Im searching for alignment spec's on a 6 cavity Celwave duplexer. Band width is 430MHz to 470MHz. The model number on the unit is as follows: 0185417U05 Its a rack mounted unit, black in color, and has Variable capacitor and tuning rod for each cavity. Ive been unable to find any white paper on this older model and was hoping maybe someone has on old catalog they could get the info from. Gary KI4VDP
