A Low VSWR 2SB Schottky Receiver [PDF]
IEEE Transactions on Terahertz Science and Technology, 2011 A novel high performance waveguide integrated sideband separating (2SB) Schottky receiver operating in the 320-360 GHz band is presented. The unique receiver design is based on a core of two subharmonic Schottky diode mixers with embedded LNA's with a minimum noise figure of 1.8 dB, fed by LO and RF quadrature hybrids.

Design of low VSWR axisymmetric subreflector
Electronics Letters, 1993 The design of a low VSWR axisymmetric subreflector using the method of moments is described. To reduce the power reflected back into the waveguide horn the surface of the hyperbolic subreflector is deformed using raised-cosine functions. The method of moments technique is then validated by comparing experimental and theoretical results.

VSWR Adjustment for ACS Cavity in J-PARC Linac
Journal of Physics: Conference Series, 2019 Abstract In the Japan Proton Accelerator Research Complex (J-PARC) linac, negative hydrogen beams are accelerated from 190 MeV to 400 MeV by Annular-ring Coupled Structure (ACS) cavities. The RF input coupler of the ACS21 cavity, which is the twenty-first (the last) accelerating cavity in the order of beam acceleration, had a ...
