Coaxial Dynamics has been heavily involved in the design
and manufacture of custom components since 1969. OEM components such as RF Filters,
Directional Power Detectors (or Couplers) Filter-Detector combinations, and PIN
Diode Switches are routinely designed for customers all around the world.
Our general range of operations covers frequencies from 2 MHz to 2500 MHz. All
devices are designed for use in 50-Ohm transmission line systems. Most are for use inside
of transmitters and transceivers. They are designed to handle power levels from
milliwatts up to several kilowatts.
Our Filter line includes Low Pass, High Pass, and Band
Pass designs. The most numerous designs we have are the Low Pass
configurations. Insertion Loss typically ranges from 0.2 dB to 0.4 dB and VSWR from 1.3 to
1.4 maximum. Stop Band levels can reach 60 dB or higher.
Most Filters are built in a box configuration, which gives the best use of available
space. At frequencies of 1000 MHz and above we use tubular structures.
Directional Power Detectors
The Directional Power Detectors come in sizes as small as 1/4" x 1/2" x
1-1/2" with more popular configurations in a box of 1" x 1-1/4" x
3". Typical output voltages are 1.0 volts across 5000-Ohms at reasonable power
levels (10 watts or greater). Most have one forward and one reflected
sensing port for DC
output voltages. Directivity of 30 dB is typical, VSWR runs 1.1 maximum, and
Insertion Loss 0.1 dB maximum in most cases.
Combinations of Low Pass Filters and Directional Power Detectors (or Couplers)
frequently been made. This provides a single VSWR and Insertion Loss specification for the
pair. Such designs typically take far less space and weight.
Designs including combinations of multiple Filters, a Directional Power
Detector, and a PIN Diode Switch are also common.
Although Coaxial Dynamics does not cover all areas of Filters and Power
Detectors, we do have considerable expertise in the areas we do handle.
We invite new inquires. Your needs may be satisfied with one of our hundreds
of existing designs available. However, if none meet your requirements, we can
design one to meet your needs.
