RF Power Termination Solution – BIRD 1210-03191 | Termaline LC40/M3/WI Series
Where This Product Is Used
The BIRD 1210-03191 Termaline Coaxial Resistor is engineered for high-reliability RF power termination across demanding industrial and broadcast environments. Typical deployment scenarios include:
- Broadcast Transmitter Testing – Used as a precision dummy load during AM/FM/TV transmitter commissioning and maintenance, safely absorbing RF output without radiating energy.
- Telecommunications Infrastructure – Deployed in base station test benches and antenna switching systems to terminate unused ports and protect sensitive downstream equipment.
- Industrial Automation RF Systems – Integrated into SCADA and process-control RF links where signal integrity and load stability are critical.
- Military & Defense RF Labs – Used in EMC test chambers and radar system calibration rigs requiring traceable, stable termination impedance.
- Research & University RF Laboratories – Standard reference load for vector network analyzer (VNA) calibration and power amplifier characterization.

Why Engineers Specify This Model
- Liquid-Cooled (WI) Design – Sustains continuous high-power operation without thermal derating, critical for 24/7 broadcast and telecom duty cycles.
- LC40 Connector Interface – Provides low-loss, high-power coaxial mating compatible with standard 7/16 DIN infrastructure, minimizing VSWR at the termination point.
- BIRD Termaline Pedigree – The Termaline series is the industry benchmark for RF dummy loads; specified by engineers worldwide for over 50 years.
- Traceable Legacy Cross-References – Cross-referenced to DSQC545A and 3HAB8101-19/07A, enabling direct drop-in replacement in legacy ABB robotics and RF control panels.
- Robust Construction – Precision-machined body with stable resistive element ensures consistent 50 Ω termination across the rated frequency and power range.

Application-Specific FAQ
Q: Can this unit replace a DSQC545A in an ABB robot controller?
A: The 1210-03191 carries the DSQC545A cross-reference. Verify connector and mounting dimensions against your specific ABB cabinet before installation.
Q: What coolant flow rate is required for the WI (water-cooled) version?
A: Refer to the BIRD Termaline LC40 installation manual for rated flow and pressure specifications. Konmask can supply the datasheet upon request.
Q: Is this compatible with 75 Ω systems?
A: No. The Termaline LC40/M3/WI is a 50 Ω termination. It is not suitable for 75 Ω cable TV or CATV infrastructure.
Q: Do you offer calibration certificates?
A: Calibration certificates are available for select units. Please inquire at the time of order.
Q: What is the maximum continuous power rating?
A: Power rating depends on coolant flow and frequency. Contact us with your specific operating conditions for a derating confirmation.
