    Model 3IFAX-1100/2250-ML is a two-channel switched filter bank from Lorch Microwave with a bypass signal path and a two-channel switched option. The bypass covers 1300 to 2250 MHz. The two-channel switch bank has a low-frequency band of 20 to 1100 MHz ...

    Model 3IFAX-1100/2250-ML is a two-channel switched filter bank from Lorch Microwave with a bypass signal path and a two-channel switched option. The bypass covers 1300 to 2250 MHz. The two-channel switch bank has a low-frequency band of 20 to 1100 MHz and a high-frequency band of 1300 to 2250 MHz. It offers 50- and 60-dB stopbands and VSWR of 1.50:1. It runs on a single +5-VDC power supply with LVTTL for control logic, and is designed for operating temperatures from -40 to +85 degrees C. The compact filter bank measures 3.2 x 1.9 x 0.35 in. with surface-mount pins.
