RF and Microwave Products
Ampleon ART2K0TFE
With great power comes great amounts of heat!
The Ampleon ART2K0 is an LDMOS that uses Advanced Rugged Technology (ART). As a 2KW RF power transistor, it has transformed the ISM, broadcast and communications markets in the HF, VHF and UHF frequency ranges however with such high powers, monitoring the temperature of the RF power transistor dies is crucial to many of these applications.
The junction temperature provides information for predicting the amplifier’s lifespan. Variations in load conditions during operation can lead to temperature fluctuations in the dies, and under extreme load changes, these fluctuations can occur rapidly.
For protective measures, such as RF drive control or swiftly shutting down the amplifier, device temperature is typically monitored using a sensor positioned on the PCB board or the heatsink close to the transistor. Its distance from the die causes inaccuracies and a time delay in temperature measurements, posing challenges for safeguarding against abrupt die temperature changes.
The innovative ART2K0TFE addresses this issue by incorporating on-die thermal sensors situated near the junctions on the dies, enabling rapid and accurate measurements for responsive control of the amplifier.
Ampleon added two small FET circuits close to the active regions of the RF Power transistor. These FET’s follow the junction temperature very closely. When a fixed voltage is connected via a resistor to one of the thermal sense pins, the sense FET conducts a temperature-dependent current. This current can be processed with an external circuit to accurately monitor the junction temperature.

Power Management Products
Knowles StackiCap MLC Capacitors
Knowles new StackiCap MLC Capacitors offer unmatched combination of case size, capacitance, and voltage and can significantly reduce PCB space for applications needing high voltage, high capacitance MLCCs. The unique design incorporates a patented sponge layer technology allowing the part to be stacked up while terminated as a single MLCC homogenous design. Typical MLCC material is brittle and subject to cracking due to the piezoelectric effect, which causes parts to vibrate when current is applied and possibly cracking the MLCC. The sponge layer helps dampen the vibration and reduce the potential for cracking.
StackiCap products are available in voltage ratings up to 2kV and capacitance options up to 5.6uF. Available case sizes include 1812, 2220, 2225, and 3640 with operation temperature range from -55C to +125C and most are available with AEC-Q200 qualification.
MRC Rolls
As the number of electrical and electronic influences in our environment increases, stricter standards for emissions are becoming more and more essential. To be able to comply with this, so that other devices are not disturbed and our health is not put under excessive strain, radiated interference must be suppressed as best as possible. As a simple, cost-effective and retrofittable solution, MRC Rolls are an important component for suppressing and absorbing such dangerous emissions. Application range for radiated emissions 30MHz to a few GHz. Filters for power range 7kW to approx. 1 MW, expandable.
MRC Rolls were selected by Diana Artero, the Sales & Marketing Manager of MRC Components, an RFMW company.
