High Power (1 KW CW) - High Isolation (35 d B) Low Loss (0.2 d B) - Very Low Distortion (IP3 = > 60 d Bm) Voltage Ratings to 1000 V PIN DIODE SWITCH Description TYPICAL CAPACITANCE vs REVERSE VOLTAGE 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 d B and isolation is greater than 35 d B (‘ off ’ state). The UM2300 series offers the lowest distortion performance in both transmit & receive modes. Less than 10 m A forward bias is required to obtain an IP3 of 60 d Bm 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 voltage 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 d B) in the ‘0 d B ’attenuator state. 130 120 110 100 90 200 KHz 100 KHz Ct (p F) 80 70 60 50 40 30 20 10 0 0 4 MHz 1 MHz 400 KHz 2 MHz Vr (VOLTS) Voltage Ratings (25° C) Reverse Voltage ( VR ) @ IR = 10 µA 100 200 400 600 800 1000 Max. 0.4 20 10 Units Ω p F µA µs d Bm DEVICE Electrical Specifications (25° C) Test Diode Resistance RS Capacitance CT Reverse Current IR Carrier Lifetime τ IP3 Min.
