RF Engineering Portfolio
RF systems, hardware integration, and measured performance.
I'm Yaniv Lieberman, an Electrical Engineer focused on RF systems and hardware integration. I work at the intersection of theory and hands-on debugging, turning complex designs into working systems.
My experience includes RF measurements, embedded systems, and automated testing. I'm particularly interested in RF characterization, system validation, and high-frequency hardware design.
Selected RF, embedded, and hardware-integration projects.
A four-layer KiCad radio design combining a Si4705 receiver, RP2040 control, USB-C power, stereo headphones, and a mono speaker, with design review and a hardware validation plan.
A 3 GHz patch-array study covering 1×2 beam steering, element spacing, grating lobes, active matching, and a 2×2 planar array with 10.11 dBi broadside realized gain.
Building a PC-controlled RF bench with HSA2307 firmware analysis, recovered spectrum traces, and an STM32-controlled ADF4351 signal generator.

A 3 GHz patch antenna integration study covering finite PCB dimensions, a physical SMA launch, radome loading, and the full mechanical assembly in HFSS.
September 3, 2026
A 3 GHz inset-fed rectangular microstrip patch antenna designed analytically and refined in HFSS, with impedance, near-field, and far-field characterization.

A third-order 3 GHz Chebyshev hairpin bandpass filter synthesized in ADS, tuned in Momentum on RO4350B, and independently validated in HFSS.
August 5, 2026
A third-order 3 GHz Butterworth coupled-resonator bandpass filter developed through ADS extraction, Momentum validation, and topology-specific HFSS optimization.
July 22, 2026
A fifth-order 3 GHz Chebyshev low-pass filter developed from lumped synthesis through ADS TLIN/MLIN, Momentum and HFSS cross-validation, and multi-parameter EM optimization.
July 8, 2026
A 3 GHz microstrip 90° branch-line hybrid coupler designed in ADS, converted to microstrip, tuned in HFSS, and evaluated for match, isolation, amplitude balance, phase balance, and usable bandwidth.
June 15, 2026
A 3 GHz two-way equal-split Wilkinson power divider designed from theory, simulated in ADS, converted to microstrip, and validated with Momentum EM/circuit co-simulation.

A Keysight ADS project exploring transmission line reflections, Smith charts, microstrip parameter sweeps, and classical impedance matching networks.
May 2026
A UART-based command-line interface for real-time interaction with STM32 firmware, eliminating the need for repeated reflashing during development and debugging.
