ATTENUATOR AND POWER PIN DIODES

RoHS Compliant Versions Available
DESCRIPTION
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.
