-- 10 Multiplier

10 Multiplier




The 9936 MHz Multiplier works in two stages.

The first stage comprises an ERA3 MMIC driven into saturation. The 4968 MHz (Input X3) is then filtered by the first edge coupled filter and amplified by the SNA586 MMIC.

The second stage uses the 4968 MHz to drive the NLB310 MMIC into saturation. The doubled output on 9936 MHz is then filtered by the second edge coupled filter, amplified (NLB310) and then split for two outputs. (Typically +6dbm to +10dbm each output).

Input frequency was designed for 1656 MHz ((X2)X3) but other frequencies (i.e. 1242 MHz (X8)) should work.

 

A Regulated +8vdc supply is needed.

 

 

VK3XDK Transverters and multipliers (Test results)

 

With Gippstech (VK3 microwave conferrence) coming up on the weekend, I quickly put together 3 kits (In one day!) for display at the event.

 

3.4 GHz Transverter and multiplier

5.76 GHz Transverter and multiplier

10.368 GHz Transverter and multiplier

 

Bear in mind these kits were built quickly and results will vary for each kit construction (better or worse)

 

All dbm measurements are taken with a 50mm rigid coax section and a sma to female n adaptor connected between the actual port and a Boonton 4B power head.

 

9936 Multiplier (for 10.368 Transverter (432 MHz IF)) Without Snowflaking

This Multiplier has an intermediate frequency of 4968 MHz

Multiplier pass band found to be 9876 MHz to 10176 MHz

 

Power out results,

-1dbm @ 1656 MHz for 7dbm (each port) at 9936 MHz

5dbm @ 1656 MHz for 9dbm (each port) at 9936 MHz
