Radio IC solution suits 60-GHz applications

The HMC6000/6001 silicon transceiver chipset targets 60 GHz applications such as metrocell/picocell backhaul, WiGig (IEEE 802.11ad) multi-Gbit/s solutions including wireless cable replacement (HDMI, USB 3.0, DisplayPort), wireless docking stations, video/magazine kiosks and wireless sensors. Fabricated with SiGe BiCMOS semiconductor process technology, the HMC6000 transmitter IC can translate analog baseband in-phase (I) and quadrature (Q) signals to a selected channel in the 60-GHz band, requiring only an external crystal oscillator.

The HMC6000 includes a low phase noise frequency synthesizer for tuning across the 57 to 64 GHz band in 500- or 540-MHz steps depending upon the reference input frequency. It features as much as 38-dB gain to achieve up to 12-dBm linear output power and 17-dBm saturated output power.

The HMC6001 receiver IC operates with single-ended input signals from a selected channel in the 60 GHz band and downconverts them to differential analog I and Q baseband signals. The receiver chip includes all necessary frequency generation, gain control, and filtering to support RF signal bandwidths of up to 1.8 GHz. It exhibits a 6-dB noise figure at the maximum gain setting and provides a 65-dB gain control range in 1-dB steps.

Both parts feature integrated phase noise of –25 dBc at the 1.76-GHz WiGig symbol rates, enabling modulation formats up to 16-state quadrature amplitude modulation (16-QAM). They both also exhibit a phase noise of typically –86 dBc/Hz at offsets 1 MHz from the carrier. (Contact company for pricing and availability)
