Velocium has introduced a transceiver chipset that operates in the 55GHz to 64GHz frequency band and delivers the performance needed to implement a full-band transceiver for high-capacity, short-haul wireless communications.

Occupying a 17mm? area, the chipset consists of an XDH158 multiplier, ALH382 LNA and driver, and the MDB207 image reject mixer that features an IF frequency range from 0Hz to 3GHz.

Also included are two RF switches (SDH126) and a power amplifier (ABH209) capable of 18dBm output saturated RF power. The LNA noise figure is <4dB across the frequency band. The chipset supports various modulation schemes and can be used in simplex, half duplex, or full duplex mode.

"There is tremendous interest in utilizing the 55GHz to 64GHz portion of the RF spectrum because of its wide bandwidth propagation characteristics that allow high-density short range links, and short wavelengths enabling very compact antenna structures," said Frank Kropschot, Velocium's COO.

Equipment developers have targeted the unlicensed 60GHz frequency band for low-cost high-capacity data and communication links for applications such as metropolitan fiber network extensions, picocell cellular backhaul, campus networks, and disaster restoration communication links.

The transceiver is priced at $150 each in quantities of 100,000 units.
