Designer Kits

Hittite has introduced five new InGaP HBT amplifiers that can now supply the Wireless Market from DC to 7 GHz. These new amplifiers come in small low cost surface mount SOT26 packages, and operate from a single positive supply. The amplifiers can be used over a wide band, or externally matched for peaked performance for narrow band applications.

Hittite's MMIC designers focused on making the amplifier family 'user friendly' and electrically robust to ensure easy implementation. Hittite's Product Validation Engineering completed a series of tests including ESD qualification, 3-temperature RF/DC characterization, and load pull stress testing on the designs. This Hittite validation process, which is unique to the industry, will ensure that Hittite's HBT Amplifiers exceed our customer's reliability requirements.

These five amplifiers offer gain levels of 12 dB to 16 dB with bandwidths of 3 GHz (HMC323), 6 GHz (HMC313), and 7 GHz (HMC315). The HMC324, a companion to the 3 GHz, features two amplifiers in a single MSOP ground based surface mount package. This allows the use of the design in a balanced configuration with superior power and 2nd harmonic performance. The 3 GHz designs can operate in 50 ohm or 75 ohm systems. Finally, the HMC314 exhibits a power level of +22 dBm from 0.5 to 4 GHz from single 5V supply. All amplifiers require minimal off-chip components; typically input and output DC blocks, pull-up choke with optional resistor and decoupling capacitors.
