Welcome to our new and featured products page.
Here we introduce our new products and some randomly selected products with unique or exceptional features.

Microwave Circuits, Inc. is now manufacturing a Helical Surface Mount Bandpass Filter, Part Number B0103131, which features a passband of 312 MHz to 315 MHz with an insertion loss of less than 5 dB at 313.5 MHz and excellent selectivity of greater than 10 dBc at 310 MHz and 317 MHz. Insertion loss is less than 6 dB and return loss is greater than 10 dB over the entire passband. The 20 Watt power handling ability and surface mounting configuration fills the unique need of telemetry transmitters and receivers, wireless radio products and base station transceivers, with a size of 1.50” W x 0.50 “ H x 2.50” L. The rugged construction yields superior vibration and shock resistance for a helical filter. The in/out pins are 0.020 ” diameter silver plated, the CNC milled housing is aircraft 6061 silver plated aluminum, and the lid is solder sealed for excellent environmental performance.

Surface Mount Lowpass filter, Part# FL0005M1

Microwave Circuits Inc. introduces the FL0005M1 Surface Mount Lowpass Filter. This filter is highly durable which features Insertion Loss of less than 1 dB from DC- 5.0 MHz, a 3 dB Insertion Loss @ 5.8 MHz Nominal. It is “virtually indestructible” with an encapsulated epoxy filling and Rejection greater than 20 DBC at 8 MHz and Rejection greater than 40 DBC at 10-200 MHz. It is conveniently priced for high reliability and long lasting use. The size is just 0.25” H x 0.38” W x 0.75” L excluding connections. This filter has bi-directional .050” tabs for your SMT applications.

Surface Mount Ceramic filters, Part# C031880E & C031960J

    Microwave Circuits, Inc. is a leading provider of high performance ceramic bandpass filters, as demonstrated by its pair of filters the C031880E and C031960J. These surface mount Bandpass filters are constructed of high dielectric constant ceramic coaxial resonators. The center frequency is precisely determined by grinding of the ceramic under CNC control. They are temperature stable low phase noise devices with center frequencies of 1880 MHz and 1960 MHz respectively with insertion loss at center frequency equal to 1 dB nominal. Electromagnetic coupling of two coaxial resonator sections forms the filter’s 0.5 dB bandwidth equal to 60 MHz minimum and 50 OHM VSWR of less than 1.5: 1 typical, ideal for your 1850-1910 & 1930-1990 MHz applications. Their compact size is just 0.26” H x 0.39” W x 0.70” L excluding tabs. These high Q filters have 0.020 “ diameter silver plated RF pins, are reflow solderable, shipped in tape and reel, and economically priced for high volume and short lead times.

High power Lowpass filter, Part# L1202701

    Microwave Circuits, Inc. introduces one of a new series of High Power Lowpass Filters. The L1202701 features a passband of DC to 120 MHz with a passband insertion loss of less than 0.2 dB. Its rugged construction can easily handle an average power of 40 Watts and Peak power of 1 kW into 50 Ohms. The filter is used for harmonic rejection at transmitter outputs to eliminate spurious emissions. The Housing is very robust with plenty of heat sinking and uses one-piece silver plated connectors that are screwed and soldered to the filter housing, and as typical of the high quality Microwave Circuits filters, has a solder sealed lid. The smooth fiinish applied is mil-aircraft quality polyurethane paint. This Low Pass Filter typically measures over 100 dB Rejection up to 1 GHz and saves equipment providers from having to use two filters in series to reach these high rejection levels. The size is 1.50” H x 1.50” W x 8.00” L excluding N female connectors and every one ships with with test data at a very affordable cost.

Highpass filter, Part# H2G406G1

    Microwave Circuits, Inc. introduces its newest High Pass Filter, the H2G406G1.
It features a passband of 2400 to 6000 MHz with a passband insertion loss of less than 1.0 dB and power handling of 100 watts continuous. Rejection spec is greater than 50 dB from DC - 2010 MHz min. The cut-off frequency is equal to 2200 MHz nominal and has a 50 Ohm Passband VSWR of less than 1.5:1. Superior performance is achieved by using a milled housing with soldered in circuit boards and silver plated wire. It uses one-piece silver plated connectors that are screwed and soldered to the filter housing. To insure the highest rejection and lowest insertion loss it has a solder sealed lid. The smooth finish applied is mil-aircraft quality polyurethane paint. The size is 1.00” H x 1.00” W x 4.00” L excluding N female connectors and every one ships with test data at a very affordable cost.
