PIN DIODE
SWITCH
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.
