Impedance Matching Filter
Transhybrid Balancing (TH) Filter
• Realization by 3 different loops
• Improved stability behavior of feedback loops
• Real part of termination impedance positive under all conditions
• Improved overflow performance for transients
• Return loss better 30 dB
• New concept: 2 loops at 16 kHz
• Flexible realization allows optimization of wide impedance range
• Consists of a fixed and a programmable part
• Trans-Hybrid-Loss better 30 dB (typically better 40 dB, device only)
• Adaptation to different lines by:
– 4 MHz:
– 128 kHz:
– 64 kHz:
– 2nd order Wave Digital Filter (IIR)
– 7-TAP FIR-Filter
– Easy selection between four different downloaded coefficient sets
