Eravant announces the SAY-3433634310-28-S1-MP, a monopulse Cassegrain antenna. Designed and manufactured for operation indoors or within an environmentally protected radome, the antenna covers a frequency range of 34 to 36 GHz. With a beamwidth of 1.0 degree and a gain of 43 dBi for the sum channel, the antenna provides E-plane and H-plane sidelobe levels of -16 dB. The minimum return loss is 13 dB on all RF ports.

The three waveguide ports provide channels for sum, vertical difference (elevation) and horizontal difference (azimuth) signals. The peak gain for the difference channels is 36 dBi. Minimum isolation between the sum and difference channels is 45 dB. The symmetrical feed structure yields excellent beam uniformity and a null depth of 30 dB for the difference channels.

The feed network includes E-plane and H-plane folded magic tees and machined waveguide sections that enable low signal loss and stable electrical performance. The antenna measures 26 inches in diameter and 14 inches in length. The reflector surface is painted and all waveguide components have a chemical finish for corrosion resistance. The WR-28 waveguide ports are compatible with UG-599/U waveguide flanges. A smaller version of the antenna, model SAY-3433632750-28-U5-MP, has a reflector that measures 4.0 inches in diameter and provides a gain of 27 dBi for the sum channel. The temperature range of both models is -40°C to +85°C.
