GCG Broadens its Range of Innovative Filter Solutions

Gowanda Components Group is pleased to announce that its capabilities for the design and manufacture of RF and microwave filters are expanding in connection with the acquisition of Microwave Circuits from AMTI in Lynchburg, VA.

“Microwave Circuits’ designs and technologies complement those of our TTE Filters business unit,” said GCG CEO Don McElheny. “The synergy in our capabilities and applications will enable us to offer a broader range of innovative filter solutions to design engineers in commercial, medical, microwave, military, space and other markets around the world.”

Terms of the deal were not disclosed but GCG has stated that Microwave Circuits’ production facilities will remain in Beltsville, MD and sales & technical support will remain in Lynchburg.

This is the fifth acquisition for GCG within the last five years.  For more information please contact Claude Badawy at +1-716-532-2234 or cbadawy@gowanda.com.

The individual business units that support Gowanda Components Group include Gowanda Electronics, TTE Filters, Instec Filters, Communication Coil, Butler Winding and now Microwave Circuits.

High Frequency, High Current and Standard Designs – to 40 GHz – for Signal Processing Applications

 

TTE will introduce a new line of Bias Tees at IMS2015. The line includes three series:

• BTHF – high frequency series for 10 MHz to 40 GHz
• BTHC – high current series for 500 MHz to 4 GHz and current handling to 7 A DC
• BTS – standard series for 10 MHz to 18 GHz

All three series provide very low insertion loss, minimal return loss, desirable VSWR characteristics and extremely flat gain response over the series-specific frequency ranges. The products are manufactured using high-quality components and processes to deliver superior broadband performance. A summary data table is provided below. RoHS-compliant parts are available upon request.

Please refer to series datasheets for the most up to date information in case any data has changed since the news release issued.

Summary Data Table for TTE Filters Bias Tees:

TTE Filters Bias Tee Part Number	Frequency Range (GHz)	Insertion Loss Typ (dB)	Return Loss Min (dB)	VSWR Min	DC Port Isolation  Min (dB)	DC Current Max (mA)

The Lowpass Chebyshev LC9S Passive Filter Series Addresses the Need for Off-The-Shelf Convenience

TTE has been manufacturing filters in the USA since 1956 and has particular expertise in short lead times.  Expedited lead time as short as 3-5 days is available on many built-to-order filter designs.  TTE’s new LC9S is a high quality filter series offered from inventory with competitive pricing and same day shipment.  This series addresses the market need of customers requiring immediate delivery – when 3 to 5 days is not fast enough.

The 9-pole filters in the LC9S Series deliver fast roll-off, an insertion loss of 1.0dB maximum and 50 Ohm terminations.  Nine part numbers are available, each at a specific -1dBc passband frequency, from 30 MHz to 3 GHz.
