Tenders Are Invited For Wideband Highly Linear And Efficient Power Amplifier Module Architecture

Tenders are invited for Wideband Highly Linear and Efficient Power Amplifier Module Architecture for 5g Active Antenna Application (Artes 4.0 Spl 5g/6g 5c.543) - Expro+ Objective: The objective of this activity is to design, develop and test wideband power amplifier module architectures that exhibithigh linearity and efficiency for active antenna covering asignificant portion of the Frequency Range 1 (FR1). The amplifier architectures must be capable of handling high crest factors, which are characteristic of the multi-carrierwaveforms proposed in 5G New Radio. The module should include the complete power amplifier chipset with housing and interfaces to beamforming network and phasedarray with flexible dynamic power control.TargetedImprovements: Enabling wideband power amplifiers (700 2700 MHz), with at least 30% Power Added Efficiency (PAE).Description: The waveform and modulation schemes used in 5G New Radio (NR) aim to provide spectral efficiency, high data throughput, and resilience required for terrestrial 5Gcommunications. Orthogonal Frequency Division Multiplexing (OFDM) offers good spectral efficiency whilst providing resilience to selective fading, however such multi-carriertechniques introduce a high Peak-to-Average Power Ratio (PAPR), which has a major impact on the efficiency of the RF Power Amplifiers (PA) as thelinear operation requireslarge output back-off. Conventional satellite power amplifier architectures without efficiency enhancement techniques can impact the power added efficiency (PAE) of thepower amplifier front-end, due to the required Output Back-Off (OBO)toachieve the desired linearity. For the OFDM waveform the amplifiers are typically operated at 6 to 8 dBOBO to achieve the desired linearity, Noise Power Ratio (NPR), and Error Vector Magnitude (EVM). This represents a major hurdle in the application of 5G NR foron-boardamplifiers with high PAPR.This activity will investigate novel PA architectures that can operate over a significant portion of the FR 1 band (i.e. from 700 to 2700 MHz), with a PAE greater than 30% andmeeting the linearity requirements. Several highlinearity and efficiency RF power amplifiers technologies and architectures will need to be investigated for the benefit of theefficiency enhancement techniques and shall be evaluated, simulated, and demonstrated at the Engineering Model level. At least two potential architectures with optimumtechnology shall be selected, designed, developed and tested to demonstrate the RF performance improvements with OFDM waveforms and their application to active antennaarrays for 5G payloads. Procurement Policy: C(2) = A relevant participation (in terms of quality and quantity) of non-primes (incl. SMEs) is required.
