IDT offers high performance millimeter wave RF and timing products for 5G wireless basestations and fixed wireless access at 26/28/39 GHz, roof-top backhaul in E-band (71 to 86 GHz), and 5G small cell LTE backhaul and fixed wireless access in V-band (51 to 71 GHz). IDT products include RF beamformers, power amplifiers and power detectors, RapidWave™ baseband modem ICs, and advanced timing solutions.

26/28/39 GHz 2 x 2 Beamformer IC Solutions

IDT's mmWave beamformer ICs are 4-element TRX half-duplex silicon ICs designed using an advanced SiGe BiCMOS process for 5G phased-array applications. The IDT chips F5280 and F5390 address the three major worldwide bands of 24.25 to 27.5 GHz, 27.5 to 29.5 GHz, and 37 to 41 GHz.

The core ICs have 5-bit and 6-bit phase control and more than 35 dB gain control on each channel to achieve fine beam steering and gain compensation between radiating elements. In transmit mode, the chips have 23 dB gain and 13dBm OP1dB. In the receive mode, the receive gain is 23dB with an NF of 5 to 7 dB and an IP1dB of -25dBm, over the band. The core chips operate at 2.1 to 2.5 V and feature ESD protection on all pins. The core design includes standard SPI protocol that operates at up to 50MHz with fast-beam switching, fast beam-state loading, and fast on-chip beam storage. The ICs also have four external bias pins (5-bit DACs) to control an optional external LNA/PA module and temperature reporting capability.

E-Band Wireless Backhaul Solutions

IDT offers a large selection of mmWave / E-band products, providing unprecedented communication performance for GNSS/GPS, microwave backhaul and satellite systems. The products include integrated broadband transceivers, transmitters, receivers as well as discrete devices such as amplifiers, power detectors and delay elements. IDT leverages a broad range of state-of-the-art processes such as GaAs, GaN, InGaP, InP and SiGe to optimize the price/performance trade-off for its customers.

RapidWave Baseband Modem Solutions

IDT's RWM6050 RapidWave modem IC provides a common modem solution to address the high frequency microwave band through the mmWave band of spectrum. The configurable radio interface provides a common platform to connect custom RF solutions to address a wide frequency spectrum. The RWM is a multi-gigabit TDD (or FDD) solution making it an ideal modem for roof-top backhaul in E-band (71-95GHz), 5G small cell LTE backhaul in Ka-band (28/39GHz) and fixed wireless access in V-band (57-71GHz) deployments.

The RWM6050 modem delivers key advantages for telecom infrastructure applications. The dual modem architecture simplifies network planning and deployment of small cells and mesh networks.  The integrated MAC and PHY, alongside a complete software kit, provide a well-defined API that delivers a rich set of attributes and functionality configurable within the modem. In addition, the system-level mixed-signal integration improves overall cost- and power-efficiency.

About Millimeter Wave (mmWave)

Millimeter wave, also known as mmWave or just mmW, is a band of spectrum that is being used in various high-speed applications including consumer, communications, defense and security. The International Telecommunications Union (ITU) has designated this spectrum 'extremely high frequency' (EHF); describing radio frequencies from 30 to 300 GHz. Radio waves in this band have wavelengths from one to ten millimeters, hence the term: millimeter wave.

The high frequency is advantageous in that it allows for more bandwidth and higher data rates, making it an attractive solution for wireless infrastructure applications. Furthermore, due to its small wavelength, mmWave experiences higher atmospheric attenuation than longer-wavelength (lower frequency) signals. While this limits its range of distance, the attenuation characteristics make it ideal for frequency reuse and enhanced information security.
