A1 waveguide assembly A1 Microwave is a UK supplier with the slogan " The world's smallest and lowest loss filters". This relates to the waveguide filters, couplers, combiners and diplexers, whose excellent quality and compact size result from the precision milling production method of A1 Microwave. The main markets are SATCOM, RADAR, radio links, communications from UHF to Ka-Band. A1 Microwave welcomes inquiries for customer specific waveguide assemblies (see picture above).

New:  Low-Loss Combiner for X-Band, 2-Way and 4-Way with low insertion loss (0.3dB) and ideal amplitude balance (0.03dB) and phase balance (0.3°).

A1 coax microwave filter New: GPS Notch Filter with 70dB rejection for the protection of GPS signals in counter-IED (jamming) applications, high input power (200W min.), low insertion loss (0.1dB at GSM900 and 0.2dB at GSM1800)
