Renesas Electronics RF Signal Chain Solution for Macro BTS Systems
Renesas Electronics RF Signal Chain Solution for Macro BTS Systems are circuit-level RF innovations for leading communications systems providers. These Macro Base Transceiver Station (BTS) RF devices have a unique circuit design to support next-generation Macro BTS development. These applications require lower Noise Figures, higher linearity, lower power consumption, and more integration for next-generation 4G architecture and rolling over to 5G applications. The Renesas portfolio delivers the high performance, high reliability, flexibility, and smaller form factor demanded by 5G Macro BTS systems. These devices are ideal for various environmental conditions and frequency bandwidths. They integrate Renesas' Smart Silicon™ innovations to enable smaller footprints for a given function.
Features
- Glitch–Free™ Technology
- Renesas' digital step attenuators (DSA) virtually eliminate transient overshoot that occurs during MSB attenuation
state transitions of standard DSAs. With Glitch–Free technology, amplifier damage and loss of information at the ADC
are avoided.
- Renesas' digital step attenuators (DSA) virtually eliminate transient overshoot that occurs during MSB attenuation
- FlatNoise™ Technology
- Renesas’ variable gain amplifier (VGA) noise figure is kept virtually flat in the critical region, while gain is reduced.
This greatly eases design constraints for radio engineers by enhancing signal–to–noise ratio (SNR)
- Renesas’ variable gain amplifier (VGA) noise figure is kept virtually flat in the critical region, while gain is reduced.
- Zero–Distortion™ Technology
- Renesas' RF amplifiers and RF mixers improve SNR by reducing the noise floor and third-order intermodulation
distortion. This is important for crowded spectrum environments, as it enhances quality-of-service (QoS) and
frees up underutilized spectrum.
- Renesas' RF amplifiers and RF mixers improve SNR by reducing the noise floor and third-order intermodulation
- KLIN Constant Linearity Technology
- Renesas' variable gain amplifiers maintain constant high linearity as gain is adjusted. As the gain is reduced, the
linearity (OIP3) remains constant in the critical region. This prevents intermodulation distortion from degrading as the
gain is reduced.
- Renesas' variable gain amplifiers maintain constant high linearity as gain is adjusted. As the gain is reduced, the
- K|Z| Constant Impedance Technology
- Renesas' RF switches maintain nearly constant impedance when switching between RF ports. By controlling the
impedance during the switching process voltage standing wave ratio (VSWR), transients are minimized. This improves
switch reliability, reduces voltage stresses on downstream components, and improves overall system performance.
- Renesas' RF switches maintain nearly constant impedance when switching between RF ports. By controlling the
- KGAIN Constant Gain Compensation Technology
- Renesas amplifiers are able to maintain near-constant gain with KGAIN technology that automatically reduces S21
variation over temperature. Allowing temperature dependence to be controlled by design provides better tolerance
and relative immunity to process variation which is particularly ideal for large-signal chains.
- Renesas amplifiers are able to maintain near-constant gain with KGAIN technology that automatically reduces S21
