NXP Launches a New Family of Discrete GaN Devices for 5G Massive MIMO

NXP recently launched a new portfolio of discrete Gallium Nitride (GaN) transistors to expand 5G Massive MIMO coverage. The transistors enable easy deployment of 5G Massive MIMO in urban and suburban areas.

NXP’s proprietary RF GaN technology is manufactured in their new Chandler (Arizona) fab and available through RFMW, their specialist RF distributor. This launch provides a GaN portfolio covering the 5G cellular bands between 2.3 and 4.0GHz.

A key benefit is that NXP’s GaN technology has a low-memory effect designed to maximizse linearity and reduce Digital Pre-Distortion (DPD) complexity.

The portfolio covers 48V driver stages, allowing a single amplifier supply voltage for the lineup. Engineers can design high-efficiency power amplifiers with optimum power consumption, size, and weight for easier deployment.

Portfolio

The portfolio covers both driver and final stage discrete GaN transistors suitable for 10 Watt 32T32R and 5 Watt 64T64R Massive MIMO antennas. Most transistors share the same DFN 7 x 6.5 package.

Renesas RF Amplifiers:

Renesas offers RF amplifiers with a variety of gain, noise figures, and linearity features in either differential or single-ended input impedances. The products feature innovative Zero-Distortion™ technology, enabling high output IP3 with very low current consumption – setting them apart from simple gain block amplifiers.

In addition, Renesas’ RF amplifiers feature built-in broadband baluns to support wide-band applications with differential inputs and outputs. The products are designed for high-reliability operation, using a SiGe amplifier die together with an integrated passive device (IPD) die and proven high-volume QFN packaging.

Renesas F0424 is a 600MHz to 5000MHz SiGe high-gain broadband RF amplifier. The combination of low noise figure (NF) and high linearity performance allows the device to be used in both receiver and transmitter applications.

It is designed to operate with a single 5V or 3.3V power supply using a nominal 70mA of ICC. With a supply voltage of 5V, the F0424 provides 17.3dB gain with +40dBm OIP3 and 2.3dB noise figure at 2600MHz. This device is packaged in a 2 × 2 mm, 8-DFN with 50Ω single-ended RF input and output impedances for ease of integration into the signal-path.

Renesas Satcom/Radar Beamformers and Low Noise Amplifiers (LNAs)

Renesas Satcom/Radar portfolio consists of a family of 2nd generation transmit/receive ICs and LNAs supporting the three popular frequency bands of Ku-Satcom, K/Ka-Satcom and Ku/CDL for satellite communications, point-to-point terrestrial communications and radar applications. These ICs maximize  antenna array performance and power efficiency while also simplifying physical implementation. The IC physical footprints are optimized for integration with a 2×2 sub-array of dual-polarized elements having λ/2 spacing. State-of-the-art built-in power management features and excellent gain/phase orthogonality and channel-to-channel isolation greatly reduce the thermal management and calibration requirements relative to other solutions, thereby enabling the lowest overall solution cost.

Tx beamformers include F6521, F6522, and F6513 ICs covering the Ku- and Ka- Satcom uplink (Tx) frequency bands of LEO/MEO/GEO constellations and the Ku radar and Ku CDL bands. For downlink (Rx), the complementary part family consists of F6121, F6212/F6122 (module/standalone BFIC), and F6123 for Ku, K/Ka, and Ku/CDL bands, respectively. Renesas Rx beamformers may be paired with the F6921, F6922, and F6923 Dual-channel Low Noise Amplifiers to provide the highest possible G/T with the lowest system power consumption.

RF Synthesizers By Renesas:

RF synthesizers generate a wide range of high frequencies from a single, typically lower, reference frequency with an internal PLL. The output frequency is controlled by accessing the digital registers in the device through an SPI interface. The output frequency is generated by a fractional or integer ratio relative to the input signal.

Renesas offers very low phase noise, low spurious RF synthesizers that address the challenges of frequency generation for high-performance mixers, modulators, and demodulators in RF board designs. The RF synthesizers are also used to directly provide a clock reference to high-speed RF converters (ADC/DAC). The output frequency range incorporates low MHz to 18GHz.

The devices feature an integrated voltage-controlled oscillator (VCO) with a large tuning range capable of providing multi-band local oscillator (LO) frequency synthesis, limiting the need for multiple narrow band RF synthesizers. This reduces the bill of materials and the design complexity, lowering the cost of developing radio frequency products. They provide solutions that address the challenges of frequency generation for high-performance mixers and demodulators in RF board designs.

The 8V97003 is a high-performance wideband microwave Synthesizer / Phase Lock Loop (PLL) that generates output frequencies up to 18GHz from an integrated Voltage Controlled Oscillator (VCO) offering an octave of frequency tuning range. The device offers a high-performance 32-bit fractional feedback divider and an output divider to allow users to fully benefit from the wideband characteristics of the VCO. The device’s figure of merit (FOM) of -236dBc/Hz and its excellent VCO performance allow for very low phase noise and RMS phase jitter. The 8V97003 offers a very low output-to-output phase skew drift of <10° across all operating conditions and frequencies, reducing radio path recalibration occurrences in beamforming applications, such as 5G radio card massive MIMO systems.

The output drivers have programmable output power settings and can deliver high single-ended output power up of +12dBm at 8GHz, and +4dBm at 18GHz, when using inductively loaded output terminations (double termination). When the outputs are resistively loaded, the output drivers can deliver a single-ended output power of +9.5dBm at 8GHz, and up to -2.5dBm at 12GHz. The output power can be further increased when using differential outputs and measuring the output power differentially. The 8V97003 relies on a single 3.3V power supply and offers low noise integrated LDOs for excellent power supply noise immunity.
