New Signal Generator

Hittite will introduce the HMC-T2270, our first 10 MHz to 70 GHz Synthesized Signal Generator. This unique and powerful signal generator was designed to support the exploding market for communication and sensor equipment operating at millimeterwave frequencies. At an output frequency of 70 GHz, the HMC-T2270 exhibits low -77 dBc/Hz phase noise, better than -46 dBc spurious output, and up to +2 dBm of output power at 70 GHz. Also on display at the show will be the HMC-T2000, HMC-T2100, HMC-T2220, and HMC-T2240 family of Synthesized Signal Generators.

The HMC830LP6GE is an industry leading low noise, wide band, Fractional-N Phase-Locked-Loop (PLL) with integrated Voltage Controlled Oscillator (VCO) that is the ultimate choice for designers looking for a single, superior performance, multi-purpose, multi-application device that can cover a wide frequency range. Ideal for wideband multi-carrier, multi-standard cellular base stations as it can be used in up or down conversion, as a low jitter clock LO generator, or as a tunable reference source for spurious free performance. It is also ideal for high QAM microwave point-to-point links, software defined radios and communications test equipment. It is capable of generating continuous frequencies from 25 MHz to 3000 MHz and features synthesizer Figure of Merit of -230 /-227 dBc/Hz in integer and fractional modes, respectively. Double sideband RMS jitter is less than 180 fs and the noise floor is -171 dBc/Hz in fundamental mode at 2 GHz.

Direct Conversion Receiver

The explosion of data in wireless infrastructure and microwave backhaul radios puts enormous pressure on equipment manufacturers to create flexible cost effective linear radios that can carry the required traffic. The solution is a compact universal wideband multi-standard, multi-carrier, radio capable of processing complex constellation signals in a crowded environment. Hittite’s direct conversion receiver line-up combines new wideband components and techniques to achieve excellent system level performance: high linearity, low noise, high image rejection, very low phase noise, accurate gain control, selectivity, flat amplitude & group delay response, adjustable bandwidth, low clock jitter and low power high dynamic range ADCs.

High Speed Multi-Mode ADC

The HMCAD1520, a High Speed, Multi-mode ADC which provides up to 12-bit resolution at up to 640 MSPS. When operated in precision mode, the HMCAD1520 provides an excellent solution for a wide variety of wireless communication applications due to its impressive resolution, sampling rate, SNR and SFDR specifications. An integrated 1- 8X clock divider, will allow the system clock to be applied directly to the ADC, which simplifies the system design and reduces BOM cost.

A combination of low power consumption, configurable number of channels, integrated cross point switches and wide range digital gain also make it an ideal choice in USB powered oscilloscopes and other test and instrumentation products. The HMCAD1520 can switch between High Speed mode and Precision mode with SPI settings. This unique feature allows the user to change the resolution and speed of the ADC with no hardware changes. The HMCAD1520 ADC is housed in a 7 x 7 mm plastic leadless SMT package.

The HMCAD1520 ADC can be evaluated with the Hittite EasySuite™ evaluation kits, EKIT01-AD1520 which is based on Xilinx® FMC (FPGA Mezzanine Card) SP601 standard motherboards, and feature Hittite evaluation boards with on-board ADCs connected to the Xilinx® board through an FMC connector. Hittite’s pre-loaded EasyStack™ firmware performs FPGA processing, while the EasySuite™ PC software tool performs ADC configuration, data capture and performance analysis.
