Configurable Switched Filter Banks
20-7500 MHz, 2 to 7 Channels, User-Configurable
API Technologies’ standard switched filter banks (310-020050-XXX series) offer customer-defined passband frequencies from 20 MHz to 7500 MHz with 2-7 channels. This series features the same high performance of a custom designed switched filter at a reduced cost.
Cost reduction is achieved by using common switch manifolds and machined parts that are populated with custom filters. The filter banks are ideal for a wide range of applications where low cost and high performance is required.
Standard Switched Filter Bank Key Features:
Switched Filter Banks with Configurable Frequency Bands
2-7 Channel Standard Switched Filter Banks
Offering customer-defined passband frequencies from 20 MHz to 7500 MHz with ultimate rejection up to 20 GHz, API Technologies’ standard line of switched filter banks can be used in a wide variety of applications where cost-efficiency and high performance is required. Their rugged construction makes them ideal for military and high-end commercial applications needing superior signal integrity, including electronic warfare (EW) and electronic intelligence (ELINT). 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.
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.
API’s switched filter banks have high isolation/rejection ( > 60 dB typical) and operate from a single +5.0V supply. Laser sealing and environmental ESS for high reliability applications as well as RoHS-compliant versions are available.
