dc block [ 163 ] 201 mclean boulevard paterson, new jersey 07504 tel: (973) 881-8800 fax: (973) 881-8361 e-mail: sales@synergymwave.com world wide w eb: http://www.synergymwave.com dc block f requency r ange: 1 - 1000 m hz dc block because of their inherent high breakdown potential, the dc blocks are ideal for applications where a high voltage, dc or ac up to 20 khz, must be rejected from the rf signal path. leakage from modulating signals can occur via ac power lines, through ground loops, or along poorly grounded coaxial cables. these leakages can impair the accuracy of rf measurements, and or signal purity. single block dual block impedance is 50 ohms for all models. note: for different connector requirements, please contact synergy. lb = lf to 10 lf mb = 10 lf to hf/2 ub = hf/2 to hf frequency insertion loss voltage vswr range (db) breakdown (mhz) lb mb ub (vdc) lb mb ub type model typ/max typ/max typ/max typ/max typ/max typ/max 3-500 0.06/0.20 0.04/0.20 0.10/0.20 2500 1.12:1/1.20:1 1.08:1/1.20:1 1.12:1/1.25:1 single blk-711n 5-500 0.12/0.20 0.10/0.20 0.12/0.25 2500 1.18:1/1.25:1 1.12:1/1.20:1 1.20:1/1.30:1 dual blk-721n 1-1000 0.20/0.30 0.10/0.20 0.40/0.50 2500 1.40:1/1.50:1 1.10:1/1.20:1 1.40:1/1.50:1 single BLK-712N 3-900 0.25/0.40 0.15/0.30 0.30/0.40 2500 1.18:1/1.25:1 1.23:1/1.32:1 1.35:1/1.45:1 dual blk-722n 158 for package outline drawing, see back pages.
