API Technologies Corp., a leading provider of high performance RF/microwave, power and security solutions for critical and high-reliability applications, introduces a new line of standard switched filter banks with customer-specified frequency bands from 2 to 7 channels.  With lead times as fast as four weeks, the configurable solution significantly reduces development cycle time, resulting in cost savings and faster time to market. 

Offering customer-defined passband frequencies from 20 MHz to 7500 MHz with ultimate rejection up to 20 GHz, these switched filter banks can be used in a wide variety of applications where cost-efficiency and high performance is required. Their rugged construction make them ideal for military and high-end commercial applications needing superior signal integrity, including electronic warfare (EW) and electronic intelligence (ELINT). 

These high performance, integrated devices use mechanically channelized PIN diode switch manifolds for lower insertion loss and high isolation, as well as lumped element filters for increased rejection, all in a space efficient footprint. They also feature integrated switch drivers with typical switching speeds of 200 nanoseconds. 

The TTL-compatible filter banks optimize several characteristics, such as VSWR and passband flatness, in a compact form factor for increased performance as compared to individual components. By using common switch manifolds and machined housings populated with custom filters, these devices are more cost-effective than fully custom solutions. Additional functionality, including gain compensation and leveling, can be added if required.

John Yania, product line manager, RF/Microwave & Microelectronics, API Technologies said, “Our new line of 2 to 7 channel switched filter banks offer the high level of performance customers expect, in the configurations they want, and the reduced time to market they need for competitive advantage.”  

API’s switched filter banks have high isolation/rejection (> 60 dB typical) and operate from a single +5.0 V supply. 

Laser sealing and environmental ESS for high reliability applications as well as RoHS-compliant versions are available.
