Renesas Electronics expanded its portfolio of mmWave solutions with the introduction of two new IC families for satellite communications (Satcom), radar, and phased array applications: the F65xx transmit active beamforming ICs and F692x low-noise amplifiers (LNAs).
Featuring a combination of low power consumption, high gain and compact size, the new solutions deliver a performance boost for antennas used in Satcom and radar systems.
The F65xx and F692x devices address thermal and integration challenges designers face as they transition from bulky mechanically scanned antennas to lower weight and profile active electronically scanned array antennas (AESAs). The two new families support Satcom, radar and point-to-point communications applications in the Ku, Ka, and CDL frequency bands.
The next generation of 8-channel F6521 (Ku), F6522 (Ka) and F6513 (CDL) Tx active beamforming ICs offers unprecedented performance in a small form factor satisfying the tight integration requirements of planar phased array antennas. They simultaneously satisfy both the effective isotropic radiated power (EIRP) and thermal dissipation requirements of terrestrial Satcom terminals operating on low/medium Earth orbit (LEO) and geosynchronous Earth orbit (GEO) satellite networks in the Ku- and Ka-band spectrum.
Additionally, higher phase and gain resolution are coupled with larger on-chip memory and advanced digital modes to enable precise beam pattern and polarization control, and rapid beam steering. The ICs share the same physical footprint as first-generation devices, reducing the required board re-design time when migrating to the second-generation ICs.
Features of the F65xx ICs include compact BGA package with a physical footprint of less than 2.2mm2/ch; single 2.3V supply simplifying power distribution network design; highly efficient operation, consuming <100 mW/ch of power at >10 dBm/ch of RF output; fast beam steering mode with <100 ns beam update times; digital controls compatible with standard 1.8V digital logic; and excellent gain/phase orthogonality and low RMS phase and gain errors.
The F6921 (Ku), F6922 (Ka), and F6923 (CDL) dual-channel LNAs offer an ideal combination of low power consumption, low noise, high gain, and compact size to maximize the antenna array G/T, while minimizing the antenna aperature’s physical size resulting in lower overall power dissipation and system cost. The LNAs feature 19 dB of gain with only 15-20 mW of power consumption and two highly isolated and gain/phase-matched RF channels in a single BGA package with 50 ohm single-ended RF inputs and outputs.
Evaluation kits and pre-production samples of the F65xx and F692x ICs are available to qualified customers starting in April.
