As wireless infrastructure evolves to support higher data rates and denser deployments, the need for compact,
efficient and high-performance solutions becomes paramount. NXP’s A5M20TG042 mid-power module is engineered to meet
these
demands
by offering a robust, space-saving solution for next-generation FDD and mMIMO systems.
Advanced Amplifier Architecture: 3-Stage Doherty Design + LDMOS and GaN
For 25 years, FDD has been known for its common usage in cellular networks because of its efficient and simultaneous
two-way communication between the user and base stations. Historically, FDD has been primarily utilized in Macro
technologies, but now NXP is improving its versatility by leveraging our A5M20TG042 amplifier in massive multiple input, multiple output
(mMIMO) applications.
At the heart of the A5M20TG042 is a 3-stage amplifier topology that combines a 2-stage laterally-diffused metal-oxide
semiconductor transistors (LDMOS) driver integrated circuit (IC) with a
gallium-nitride–based (GaN) Doherty final stage. This hybrid architecture enables:
- High linearity and power-added efficiency (PAE) across a wide dynamic range
- Peak-to-average power ratio (PAPR) handling, ideal for modern modulated signals such as long term evolution
(LTE) and 5G new radio (NR)
- Doherty configuration that dynamically adjusts load impedance to maintain efficiency at back-off power
levels—critical
for systems with high crest factor waveforms
The A5M20TG042 leverages LDMOS for its proven reliability in driver stages, while incorporating GaN in the final
stage
for its high electron mobility, enabling faster switching and higher frequency operation. Additionally, GaN offers
excellent thermal conductivity, allowing for higher power densities, and a high breakdown voltage that supports
robust
performance under high-voltage conditions. This combination ensures optimal performance across the 1800–2200 MHz
band,
delivering 49% efficiency at rated power and 42% efficiency across the lineup.
