Description

The PSF-030 is a thin film analog voltage controlled attenuator providing 30 to 50 dB of range depending on frequency and flatness require- ments. It uses PIN diodes in a modified Pi configuration to maintain low VSWR perfor - mance over the control range. The PSF-030-25 comes in our smallest hermetic surface mount package and offers higher performance than the PSF-030-45. RF OUTRF IN +15 VC Technical Data
