Endwave Corporation has released a transmit-receive module pair that operates over the E-band frequency spectrum from 71.0 to 86.0GHz. These modules enable broadband point-to-point radios to carry voice and data traffic at multi-gigabit per second rates.
The typical performance of 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. 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 to 76 and 81to 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. Endwave’s E-band MLMS mixer design provides functionality and performance that is not even available in MMIC format today. This architecture significantly reduces the cost of the local oscillator (LO) circuit chain relative to the costs of comparable fundamental mixer approaches.
