SP10 - 10 MHz Splitter 

Orbital Research introduces the SP10 - 10 MHz Splitter, a System Interface Product (SIP), that enables 3 Way - 0° splitting of the 10 MHz reference signal, with under 7 dB of insertion loss, while providing over 30 dB of isolation, and a VSWR of under 1.5, at 10 MHz. 

The 10 MHz Splitter can be combined with other SIP products, such as the MOS - Master Oscillator, the MOM - Master Oscillator Module, and the POP - Precision Oscillator Module so that multiple devices can be locked to the same precise 10 MHz reference. 

The Problem:

Stability, phase noise, drift, bit-error rate, offset – all problems you have determined can be solved with a good external reference LNB. You have chosen a high quality oscillator as your 10 MHz source, but how do you hook them all together?  You may have a BUC and two LNBs all needing 10 MHz – you’ve spent all this money to get quality components, but that can all blow away if you don’t hook them up properly.

Enter the SP10 – 10 MHz Splitter – it will divide the output of the oscillator, feeding equal amounts of signal to up to three devices with minimal loss.  However, it is imperative that each device does not contaminate the other – this is called isolation - and you most definitely do not want switching noise from a BUC traveling back into your LNB.  Each device can have peculiarities that can seriously effect the other.  Equally important, is that the process of delivering a quality reference to each device does not add noise, ground-loops, modulation, or any other degradation of the reference signal. 

Splitting is simple; keeping it split is the challenge met by the SP10 – 10 MHz Splitter.  Remember the 20 log n lesson, where n is the number of times the 10 MHz reference signal is multiplied to lock your local oscillator - if you have a 10 billion cycle signal controlled by a 10 million cycle reference, any problem at 10 billion cycles is a thousand times worse.
