First wideband production Millimeter-Wave tuneable notch filters from Micro Lambda Wireless
20 - 36 GHz and 28 - 40 GHz YIG-Based Notch Filters for EW and ECM available from APC Technology
Micro Lambda Wireless, Inc. has developed a breakthrough Notch filter line that covers Millimeter wave frequencies. This family of new Yittrium Iron Garnet-based filters provide superior notch depths over the 20 to 40 GHz frequency range. Two models offer tunable notches of 15 MHz minimum at 40 dB down across the 20 to 36 GHz (MLFR-2036) and 28 to 40 GHz (MLFR-2840) bands. The 3 dB Bandwidth is 100 MHz max. for both models. Typical passband insertion loss is 3 dB, and the passband range is 20 to 42 GHz.
The frequency of the filters is changed by changing the current across the tuning coil which has a sensitivity of 25 MHz /mA. They use an internal heater that operates off of either +28 Vdc or +/- 12 to+/- 14 Vdc. Surge current typically is 300 mA max and less than 100 mA steady state.
Over the temperature range of O C to +60 C the frequency drift is +/- 20 MHz while the linearity is +/- 5 MHz over the frequency range.
MLFR Series Millimeter-Wave
YIG Band Reject Filters | 20-40 GHz
- 20-36 and 28-40 GHz Full Band Coverage
- Excellent Linearity
- 1.7” Low Profile
The Micro Lambda MLFR-Series of Millimeter-Wave Band Reject filters cover the frequency range of 20 GHz to 40 GHz in bands. These filters offer excellent notch depth and precise bandwidths for rejection of unwanted signals. 3 dB bandwidths are 100 MHz with 40 dB bandwidths of 15 MHz available in standard designs.
These filters are well suited for broadband receivers and a variety of EW system applications. Standard configuration of 2.0" x 1.7” are provided and can also be ordered with an Analog, TTL Digital or Serial Driver.
