Highly efficient,
frequency selective dividers and combiners are typically a series
of lowpass-highpass crossover junctions. The complexity usually ranges
from one to four crossover junctions, in addition to close-up lowpass
and highpass filters. Integrated Microwave is the leader in small,
high-performance lumped element, combline, interdigital and suspended
substrate multiplexers- including phase- and amplitude-matched designs.
Multiplexers are available in narrow, moderate, and octave passbands. Typical multiplexers will have a 1.5:1 maximum passband VSWR and a 2.0:1 maximum crossover VSWR.
Integrated Microwave can provide a customized solution promptly and at very competitive pricing.

Combline/Interdigital(ICBP) and Waveguide (IWBP) Series
Integrated Microwave has the technology to model and produce waveguide
filters that are capable of meeting both group delay and amplitude
specifications simultaneously, without the use of separate equalizers.
These waveguide filters are achieved using either post or iris inductive
suseptances. These filters can be designed to meet VSWR and attenuation
specifications very nearly equal to more conventional Chebyshev or
Butterworth designs while maintaining a low group delay variation
over a large percentage of the passband. Insertion loss variation
over the passband will closely track the group delay variation.
