YIG Super Notch BRFs

New YIG Tuned BRF patented technology gets closer to the ‘perfect notch'. Leveraging a long heritage of engineering innovation in YIG technologies, Teledyne Microwave Solutions (TMS) has developed a line of YIG Tuned Band-Reject Filters powered by patented new technology that overcomes many long-time design limitations inherent to YIG Band-Reject or “notch” filters. Our new line delivers major advancements and unequalled performance.

TMS Super-Notch YIG Band-Reject Filters At-A-Glance

FREQUENCY RANGE: 125MHz – 18GHz
PASSBAND NSERTION LOSS: ≤1.5dB – ≤1.6dB
PASSBAND RETURN LOSS: ≥ 10dB
MAXIMUM 3dB NOTCH BANDWIDTH: 50MHz – 125MHz
INPUT POWER MINIMUM: 0 – +10dBm
TUNING SENSITIVITY: 10-20 MHz/mA

These Super-Notch Band-Reject Filters operate in the 125MHz to 18GHz frequency range, and deliver improved performance at lower frequencies with reduced spurious responses. Using these filters, engineers can overcome current limitations and achieve a previously unachievable trifecta: wider notch bandwidth plus greater notch depth plus narrower 3dB bandwidth.

KEY FEATURES

Increased minimum rejection bandwidths and notch depth at lower frequencies vs. standard band-reject filters
Reduction in the maximum 3dB bandwidth at higher frequencies vs. standard band-reject filters
Reduction in spurious responses across the board
Higher frequency bands available up to 20 GHz
