25 or 27MHz PLL for 10GHz LNB
Application: Low cost TVSat LNB disciplined to 10MHz reference
Using commercial TVSat LNBs to receive signals in the 10GHz radioamateur segment is nothing new. Since new PLL based LNBs were launched to market to fit the HD needs for better stability they proved to be useful for Rx of narrow signals like CW and SSB. Size, price and sensibility of this devices are unbeatable. But one problem is that they use a simple quartz crystal as internal PLL reference,so the long term stability is poor. Temperature variations when operating outdoor make it drift slowly and constantly. One never knows exactly which is the frequency tuned in a received signal
Finally we can say that this problem has an easy and economic fix.
Solution is a 27MHz PLL disciplined with a 10MHz reference
Stability and precision will be as good as the 10Mhz Reference used.

Voltage Variable Attenuator for up to 3,5GHz.
High Isolation Switches either SPST = just ON/OFF
or SPDT = RX/TX version

Sometimes it is desirable to have an Oscillator tunable over a specific Frequency Range. A VCO with a 11turn poti can do that job.

Or a switchable Crystal Oscillator from 10MHz to 73MHz in 1MHZ steps. A second output pin delivers F/2, means from 10 to 36,5Mhz in 500KHz. Available also with 10MHz TCXO for improved frequency stability. Output is +13dBm Square Wave. Single Frequencies with optional Low Pass Filter and Sinus Out available too.
