Clark, Finisar’s Executive Vice President for Technology and Global R&D. “We are even more excited about the potential to use this technology to help drive data rates higher than 100 Gb/s and form factors smaller than the CFP2 module and enabling new market applications in both telecom and datacom.”
Hittite reveals GaAs telecom devices for 5.5 to 8.6 GHz
The firm’s new gallium arsenide based SMT I/Q Upconverter and 2 W power amplifier are ideal for microwave radio, radar & SATCOM applications
Hittite Microwave Corporation has launched a new GaAs MMIC I/Q Upconverter and GaAs MMIC Power Amplifier.
The devices are ideal for high capacity point-to-point/ point-to-multi-point radios, SATCOM and radar systems covering the 5.5 to 8.6 GHz frequency range.
The HMC6505LC5 is a compact GaAs MMIC I/Q Upconverter that provides a small signal conversion gain of 15 dB with 22 dBc of sideband rejection. Available in a leadless RoHS compliant SMT package, the HMC6505LC5 utilises an RF amplifier preceded by an I/Q mixer where the LO is driven by a driver amplifier. IF1 and IF2 mixer inputs are provided and an external 90° hybrid is needed to select the required sideband.
With an excellent Output IP3 of +41.5 dBm, the HMC7357LP5GE is ideal for linear applications demanding +35 dBm of efficient saturated output power. The HMC7357LP5GE amplifier features RF I/ Os are internally matched to 50 Ω, and it is available in a compact leadless 5 x 5 mm plastic surface mount package.
Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order.
GigOptix closes public offering of common stock
The net proceeds from the offering are expected to be used for working capital and other corporate purposes and possibly licensing or acquiring intellectual property or technologies
On December 24th 2013, GigOptix, Inc., closed a public offering of 9,573,750 newly issued shares of common stock at a price to the public of $1.42 per share.
Gigoptix is a supplier of advanced semiconductor communications components for use in Cloud connectivity, data centres, and high-speed optical and wireless networks.
This I/Q mixer topology is highly beneficial for microwave radio applications, since the unwanted sideband filtering is reduced. The HMC6505LC5 is a much smaller alternative to hybrid style single sideband upconverter assemblies, and exhibits excellent LO to RF rejection of 14 dBc with output IP3 as high as +35 dBm.
The HMC7357LP5GE is a GaAs pHEMT MMIC Medium Power Amplifier that operates between 5.5 and 8.5 GHz. The amplifier provides 29 dB of gain and +35 dBm of saturated output power at 34% PAE from a +8V supply.
The number of shares sold in the offering includes the underwriter’s full exercise on December 24th, 2013 of their over-allotment option of 1,248,750 shares of common stock. The net proceeds to the company from the offering were approximately $12.6 million after underwriting discounts and commissions.
The company expects to use the net proceeds from the offering for working capital and other general corporate purposes. Gigoptix may also use a portion of the net proceeds for licensing or acquiring intellectual property or technologies to incorporate in its products, capital expenditures, to fund possible investments in and acquisitions of complementary businesses, partnerships, and minority investments.
