A millimeter-wave odd-harmonic frequency multiplier comprising:
- (a) a block member of metallic material, said member having a main surface and a top surface at an angle to said main surface,
- (b) a wave-guide RF output port extending from said main surface part way through said member, said port having a rectangular cross-section of constant width and with a first portion of said port adjacent to said main surfaces having a height selected in accordance with the desired frequency output of said multiplier and the remainder of said port having a height substantially reduced from that of said first portion,
- (c) an RF input port extending from said top surface through said block member to connect with said remainder of said wave-guide port,
- (d) low pass filter means insulatively positioned in said input port, and
- (e) a pair of anti-parallel diodes positioned at the junction of said remainder of said wave-guide output port and said RF input port,
- whereby said multiplier functions, upon a millimeter-wave signal of a base frequency being applied to said RF input port, to produce an output signal at said RF output port of an odd-harmonic of said base frequency.

A millimeter-wave frequency tripler comprising:
- (a) a block member of metallic material, said member having a main surface and a top surface at an angle to said main surface,
- (b) a wave-guide RF output port extending from said main surface part way through said member, said port having a rectangular cross-section of constant width and with a first portion of said port adjacent to said main surfaces having a height selected in accordance with the desired frequency output of said multiplier and the remainder of said port having a height substantially reduced from that of said first portion,
- (c) an RF input port extending from said top surface through said block member to connect with said remainder of said wave-guide output port,
- (d) low pass filter means insulatively positioned in said input port,
- (e) a pair of anti-parallel diodes positioned at the junction of said remainder of said wave-guide output port and said RF input port, and
- (f) a metallic flange member attached to said block member at said main surface thereof and having a RF output port positioned in register with said wave-guide output port of said block member,
- whereby said multiplier functions, upon a millimeter-wave signal of a frequency of X being applied to said RF input port, to produce an output signal of a frequency of 3X at said RF output port of said flange member.
