RFE Inc. has designed a convenient, cost-effective 18 to 40 GHz frequency doubler with a bypass mode.  The input 0.5 to 20 GHz (+10 dBm input) is doubled using a passive multiplier with Gain and Filter Blocks. 

  The output 18 to 40 GHz produces +10 dBm with the Bypass mode having -5 dB loss. The output is divided into three sub-bands allowing harmonic filtering of -40 dBc.  There is also fast blanking (10 usecs) of the doubled output.  The unit is hermetically sealed and is 2.4 x 1.9 x 0.4 inches.  The unit runs off of +/- 5 Volts at 2W.  Contact RFE today.
