Micro Lambda Wireless, Inc. has developed a new Yttrium Iron Garnet-based filter that provides superior notch depths over the 6 to 18 GHz and 6 to 20 GHz frequency ranges. This new filter provides a tunable notch of 80 MHz minimum at 40 dBc down. The 3 dB bandwidth is 250 MHz maximum with a typical passband insertion loss of 2.2 dB. These filters target EW and ECM applications.

The frequency of the filter can be adjusted by changing the current across the tuning coil which has a sensitivity of 19 MHz/mA. The filter uses an internal heater that operates from either a +28 VDC supply or ±12 to ±14 VDC supplies. Surge current typically is 300 mA maximum and less than 100 mA steady state.

Over the temperature range of 0°C to +60°C, the frequency drift is 15 MHz while the linearity is ±5 MHz over the frequency range. Extended temperature models are available over the -40°C to +85°C range. Units can also be ordered with analog or digital drivers.

Micro Lambda Wireless was founded to supply the microwave community with technically superior products at reasonable prices with the highest regard for customer service and quality. Products include YIG oscillators, YIG bandpass and band-reject filters, frequency multipliers and frequency synthesizers. Micro Lambda Wireless is the largest independent supplier of YIG components in the world with over 20,000 YIG-based components and assemblies delivered annually.
