YIG Filters Tune From 8 To 18 GHz

June 25, 2009

The model M3043D bandpass YIG filter with 12-b digital driver and model M3043DD bandpass YIG filter with analog driver from Omniyig feature minimum 3-dB bandwidth of 25 MHz from 8 to 18 GHz. Maximum passband insertion loss is 6 dB while minimum off-resonance isolation is 80 dB. The filters incorporate four stages and hold passband spurious and ripple to 2.5 dB. The frequency drift versus temperature from 0 to +55C is 15 MHz. The minimum limiting level is +10 dBm. Linearity is 15 MHz while hysteresis is 12 MHz. The filters operate with driver voltage of 15 VDC and steady-state heater current of 100 mA at +24 VDC. Units with analog driver (and 9-pin connector) measure 1.7 x 1.95 x 3.2 in. while filters with 12-b digital driver (and 25-pin connector) measure 1.7 x 1.95 x 4.0 in.
