Why Embedded Resistors Matter for Satellite Design
Three challenges shape every satellite electronics decision: mass, reliability over mission lifetime, and performance at high frequencies. Embedded resistor technology addresses all three.
Mass reduction
Every gram launched to orbit carries a cost, and PCB area reduction translates directly to mass reduction. Embedded resistors eliminate the package mass, terminations, and routing footprint of discrete components, and have been documented to reduce PCB area by up to 40% in high-density designs. For satellite payloads with dense resistor counts (beamforming networks, attenuator arrays, feed structures), the mass impact is meaningful.
Reliability through the elimination of solder joints
Solder joint fatigue is one of the most common early-life failure modes for surface-mount passives. SMD resistors have been documented to account for roughly 25–30% of passive component failures in early-life electronics. Because embedded resistors are integrated within the PCB lamination, physically protected from vibration, thermal cycling, and mechanical shock, they remove this failure pathway entirely. There is no solder joint to fail.
RF performance at satellite frequencies
Commercial satellite payloads increasingly operate at Ku-band, Ka-band, and millimeter-wave frequencies where parasitic inductance and capacitance from discrete components degrade signal integrity. Embedded resistors deliver less than 0.1 nH of parasitic inductance and less than 0.05 dB of insertion loss at 40 GHz, performance levels that are difficult or impossible to achieve with surface-mount passives at these frequencies.
Satellite Applications for Ohmega Ticer Materials
Embedded resistor technology supports a wide range of commercial satellite designs:
Phased array antenna feed networks

Wilkinson power dividers and combiners
In transponder and beamforming circuits
Embedded RF attenuators
For gain balancing across satellite payloads, validated in published research up to 60 GHz
Termination resistors
In high-speed digital interfaces aboard satellite buses
Heater elements
Built from resistive foil for thermal management of sensitive components
Resistive cards (R-cards) and frequency-selective surfaces
In reflector and absorber designs
Which Ohmega Ticer Products Fit Satellite Applications
OhmegaPly® (NiP)
Five decades of continuous production heritage in mission-critical electronics. Sheet resistivities from 10 to 377 Ω/□.
TCR® (NiCr / NCAS / CrSiO)
Tight temperature coefficient (low RTC) and resistor values from 10 ohms to 100k ohms. The CrSiO formulation provides 1000 Ω/□ sheet resistivity for high-value resistor applications.
TCR-EHF®
Optimized for mmWave and high-speed satellite payloads where insertion loss must be minimized through the millimeter-wave bands.
Aerospace-Grade Quality and Compliance
Ohmega Ticer materials are manufactured under an ISO 9001 and AS9100-certified quality management system, with sample electrical testing on each lot of resistivity to ensure consistent performance. All OhmegaPly® and TCR® RCM materials are RoHS and REACH SVHC compliant. Resistive foils are profiled and tested across a wide variety of resin systems, including standard, high-performance, lead-free, and specialty resins.
Performance has been characterized to MIL-STD-202 thermal shock (−65°C to 125°C), humidity (40°C/95% RH), solder float (260°C), and load life cycling protocols. These are the baseline qualification environment for space-rated electronics.
Design Considerations for Satellite Programs
Material selection for satellite applications should account for radiation environment, expected thermal cycling profile over mission life, and the specific resin system used in the laminate stackup. Ohmega Ticer materials are qualified on a range of high-performance laminates including PTFE-based substrates for high-frequency designs and PPO-based laminates for mmWave applications.
