UM2100 ® TM ATTENUATOR AND POWER PIN DIODES 2 – 30 MHz RoHS Compliant Versions Available KEY FEATURES UM2100 Series PIN diodes are designed for transmit/receive switch and attenuator applications in HF band (2-30MHz) and below. As series configured switches, these long lifetime (25μs typical) diodes can control up to 2.5 kW, CW in a 50 ohm system. In HF band, insertion loss is less than 0.25dB and isolation is greater than 32dB (off-state). The UM2100 series offers the lowest distortion performance in both transmit and receive modes. Less than 50 mA forward bias is requires to obtain an IP3 of 60 dBm at 300 kHz with 1 watt per tone. The forward biased resistance/reactance vs. frequency characteristics are flat down to 10 kHz. The capacitance vs. reverse bias voltage characteristic is flat down to 2 MHz. In attenuator configuration, the UM2100 produces extremely low distortion at low values of attenuator control current, and very low insertion loss (0.2dB) in the “0dB” attenuator state.
