IFM-1R block


The IFM-1R is a low noise multiplier module, which combines a low noise multiplier, bandpass filter, amplifiers and a voltage regulator to achieve exceptionally low phase noise, excellent spectral purity and good conversion efficiency. Multiplication factors of 2, 3, 4, 5, 7, 9 and 11 are available with an output frequency to 16 GHz. The IFM-1R provides input referred phase noise floors as low as -176 dBc/Hz. A low noise voltage regulator is included to assist with power supply spurious signal suppression. Please consult our technical staff for assistance in configuring a multiplier to suit your needs.
