To enable broadband point-to-point radios to carry voice and data traffic at multigigabit per second rates, Endwave Corp. has released a transmit-receive module that operates over the E-Band frequency spectrum from 71-86GHz.

Endwave's transmit module includes a conversion gain of 15dB and an output power of 16dBm, with an integrated power detector on the Tx output. Higher-power transmitter options are also available upon request.

Endwave's E-Band receiver provides a noise figure (NF) of 9dB, better than 25dB of RF-to-IF conversion gain, and an input one dB compression point (P1dB) of -25dBm. Separate models cover the 71-76GHz and 81-86GHz operating bands.

Both Tx and Rx use an MLMS sub-harmonic mixer topology that provides a single level of conversion direct from E-Band to IF. According to Endwave, its E-Band MLMS mixer design delivers functions and a performance level that is not available in MMIC format today. In addition, it significantly reduces the cost of the local oscillator (LO) circuit chain relative to the costs of comparable fundamental mixer approaches, it said.

The E-Band Tx/Rx modules employ both of Endwave's proprietary technologies, MLMS and Epsilon packaging, in a single RF subsystem.
