SquareTrade © AP6.0STELLEX YIG OSC. + Synthesizer + Cable 8.0 to 10.0 GHz Tunable Stellex’s YIG [Yttrium Iron Garnet] technology provides a frequency source with high spectral purity for high-frequency communications applications. MiniYIG Tuned Oscillators • 9 GHz in Center Frequency • Low Phase Noise • –105 dBc/Hz @ 10K (typ.) • –128 dBc/Hz @ 100K (typ.) • Up to ±1GHz Tuning Range • Output Power +14.5 dBm (typ.) • Outstanding Phase Hit Performance in 64 and 128 QAM Radio Systems • Offered in SMA Connector Package Here is the pinout: 1 Red +Vcc 2 Black GND 3 Violet Tuning Coil+ 4 Orange Tuning Coil- 5 Yellow Modulation Coil 6 Gray Modulation Coil Vcc 8.5v Without tuning current the typical output frequency is 9 GHz. The YIG and PLL board combine to give you a signal from just over 8.0 GHz to about 10.0 GHz with a level of around +13dBm. The PLL controller contains a 10MHz reference and allows the YIG output to be set in precise steps of 1MHz across the 8 to 10 GHz range. Please see the excellent work that has been done by John Miles, KE5FX, his web page describes his work at http://www.thegleam.com/ke5fx/stellex.htm He has generously made his his code and documentation available for download at: http://www.thegleam.com/ke5fx/stellex/stellex.zip. The documentation includes the schematics for the controller, YIG datasheets and code in C++ PLL Board Pin out: (20-pole header on PLL board) 1_ gnd 2_ gnd 3_ gnd 4_ gnd 5_ +5V 6_ +5V 7_ Clk (I^2Cbus) 8_ NC 9_ NC10_ DATA (I^2Cbus) 11_ YIG on/off*) 12_ LE (I^2Cbus) 13_ NC 14_ FO/LD output of LMX chip 15_ +8.5V 16_ +8.5V 17_ GND 18_ GND 19_ 10MHz. ref. out 20_ Tune Ref. 0-2.5V NOTE: 20 Pin header is included. *) connect 5V via 1kOhm to pin 11 for YIG on. THIS ITEM IS 100% GUARANTEED FUNCTIONAL USA Shipping is $6.00 The controller contains a DC-12GHz divide-by-4 prescaler chip and front end MMIC amplifier (so would also make a great input for a sensitive microwave frequency counter even without a YIG). This is followed by a NatSemi synth chip LMX2326 which can be driven from a PC using NatSemis free Codeloader software, or from your favorite microcontroller (or from the KE5FX code.) I have had a lot of success with these units - the onboard 10MHz (TCXO) oscillator is OK, but for other than basic experimentation you'll want to either phase lock it to an external 10MHz source (both control voltage and output are available on pins on the controller) or replace it altogether.
