BROADBAND FREQUENCY RANGE - 1.0 TO 4.0 GHz in 3dB model. DIRECT READING SCALE-Insertion loss scales are individually calibrated. A permanently attached table shows small corrections to the calibrations above and below mid-frequency. CONTINUOUSLY VARIABLE - Attenuation is continuously variable over near linear scale using a simple slide control. SMALL PHASE SHIFT-Total insertion length remains constant for all attenuation settings, resulting in very small phase shift vs. attenuation 1 /dB/GHz. NON-CONTACTING CONTROL DEVICE- Attenuator control is capacitively coupled to attenuating element to avoid wear and insure smooth operation. STABILITY- These attenuators containWeinschel Associates high quality, stable film resistors on a ceramic base End connectors are in excellent condition. |
