Press Release from Planar Monolithics Industries, Inc.

May 5, 2014

Frederick, Maryland - Planar Monolithics Industries, Inc., a world leader in state-of-the-art hybrid MIC/MMIC components and subsystems, announces the release of its latest high-power reflective switch. 

PMI Model No. P2T-1G1R1G-25-R-TFF-40W is a single pole, two throw, hermetically sealed, reflective switch designed to operate over the 1.0 to 1.1GHz frequency range. This model is designed to handle 40 watts average input power and 4KW peak having a 3usec pulse width and 1% duty cycle. The switch offers fast switching speeds of 300nsec maximum, low insertion loss of 0.4dB typically and high isolation of 37dB typically. The DC supplies are +50VDC, 18mA typical and +5VDC, 63mA typical. The housing measures 3.92" x 2.68" x 0.70" and is supplied with TNC Female connectors.
