cHAlpha Features @ Industry Standard Outlines @ Designed for High Performance Switches & Attenuators @ Single and Dual Diode Configurations @ Low Inductance Designs for Microwave Applications @ Priced for High Volume Commercial Applications @ Available in Tape and Reel Packaging Description The SMP1300 series of surface mount PIN diodes are designed for high volume RF control applications from 1 MHz to beyond 2 GHz. Package offerings include SOT 23, SOT 143 and the small footprint SOD 323 all aggressively priced for commercial applications. The PIN switching diodes are designed for low loss, high isolation performance with switching speeds faster than 100 nS. The SMP1320 devices have been specially designed for low current drain wireless applications above 800 MHz. The PIN attenuator diodes are designed for wide dynamic range, low distortion applications from frequencies lower than 10 MHz in PI, TEE and reflective circuit topologies. Package Models The inductance of a conventional SOT 23 package is typically 1.56 nH between terminals. Alphas low inductance SOT 23 package employs an internal Plastic Packaged Surface Mount PIN Diodes SMP1300 Series SOD 323 SOT 23 SOT 143 Maximum Ratings Operating Temperature: 65 to 125 C Storage Temperature: 65 to 125 C Power Dissipation: 250 mW (At 25 C Lead Temperature) Junction Temperature: 150 C wiring configuration that reduces the inductance to approximately 0.4 nH. To benefit from this design in a shunt connected switch, the microstrip trace should be split between pins 1 and 2 with pin 3 connected to ground. The low inductance is achieved by inserting most of the package inductance in series with the transmission line rather than in shunt where it would be more detrimental. Typical isolation of 20 dB may be achieved at 900 MHz using the SMP1320-07 PIN diode, at 10 mA forward current, ina shunt connected switch employed in this manner. The following table lists the effective typical inductance of Alphas plastic packaged PIN diodes. The values were derived from Sparameter measurements and validated in a shunt connected switch employing a 50 ohm Duroid microstrip line.
