Calculated from bt2 = (out2 – in2) BTN0040 [5.0] .20 [1.70] [5.97] Ø.067 Thru .235 [11.94] .470 4 PL [1.27] .050 .370 [9.40] [11.94] .470 [9.9] .39 [5.08] .200 [3.43] .135 [MM] INCH PROJECTION XXX=±.005 XX=±.02 The BTN-0040 is constructed using a custom-made, resonance-free conical inductor to achieve extremely broadband performance. By minimizing the overall inductor size and using proprietary p ackaging techniques, the BT N-0040 is a superior option in terms of performance, reliability and ease -of-use when compared to cumbersome self-made bias tees employing off -the-shelf conical inductors. The extremely low cutoff and resonance free operation makes the BT N-0040 suitable for biasing amplifiers, lasers, and modulators driven with high frequency data patterns.
