A. Agarwal et al., DESIGN, ANALYSIS, AND DEVELOPMENT OF A HIGH-POWER, LOW-LOSS LUMPED COUPLER FOR VHF APPLICATIONS, Microwave and optical technology letters, 5(5), 1992, pp. 240-246
Lumped constant branch line couplers are analyzed and compared with co
axial branch line couplers. The effect of resistances associated with
inductors and capacitors on the coupler's performance is studied. Thre
e high-power lumped couplers of 3 dB, 6 dB, and 10 dB are designed at
53 MHz. Insertion loss of less than 0.1 and 40-kW peak power handling
capability is achieved.
