UM2100
ATTENUATOR AND POWER PIN DIODES (2-30 MHz)
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 the 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.
