Description
UM2300 Series PIN diodes are designed for transmit /
receive switch and attenuator application in LF band
( 100 KHz ) and above. As series configured switches,
these long lifetime (80 µS typ) diodes can control up to
2.5 KW CW in a 50 ohm system. In MF band, insertion
loss is less than 0.2 dB and isolation is greater than
35 dB (‘off ’state).
The UM2300 series offers the lowest distortion perform-
ance in both transmit & receive modes. Less than 10
mA forward bias is required to obtain an IP3 of 60 dBm
at 150 KHz with 1 watt per tone. The forward biased
resistance/reactance vs. frequency characteristics are
flat down to 10 KHz. Capacitance vs. reverse bias volt-
age characteristic is flat down to 1 MHz.
In attenuator configurations, the UM2300 produces
extremely low distortion at low values of attenuator
control current, & very low insertion loss ( 0.2 dB) in
the ‘0 dB ’attenuator state.
