Product Description STCA series smart temperature compensation attenuators provide temperature-variable attenuation based on thick-film thermistor elements on alumina substrates, enabling passive gain compensation across temperature extremes. With a compact footprint, rugged construction, protective coating, and operation from DC to 6 GHz, STCA series attenuators are ideal for RF and microwave circuits, supporting amplifier linearization, gain stabilization, level control, and temperature-sensitive signal conditioning applications. These attenuators are available with negative temperature coefficients from -0.003 to -0.010 dB/dB/°C in 0.001 dB/dB/°C increments, with attenuation values from 1 to 10 dB in 1 dB steps. They are offered with multiple mounting configurations—planar, single wrap, triple wrap, and gold terminations—to support both surface-mount assembly and gold-wire or gold-ribbon bonding. The thick-film resistor network determines attenuation based on thermistor material properties, laser-trimmed resistance values, and substrate thermal characteristics. These devices can fully replace imported products of the same series and type.

Product Description General-purpose temperature compensating attenuators are mainly used in RF and microwave circuits for amplifier gain compensation, gain stabilization, and level control. They feature temperature-variable attenuation, rugged thick-film construction, and an applicable frequency range from DC to 6 GHz.   Both negative and positive temperature coefficient versions are available, with attenuation values from 1 to 10 dB in 1 dB steps. The bondable gold terminations are suitable for gold-wire and gold-ribbon bonding.
