Skyworks Solutions (Woburn, MA) has introduced a miniature 0402 PIN diode for attenuator and transmit/receive switching applications. The SMP1302-040LF is a small form factor, low profile, discrete surface mount technology packaged solution that is ideal for the handset, WLAN, CATV/Satcom, land mobile radio and infrastructure markets. This diode offers very low insertion loss, good isolation, low inductance and fast switching in a very small package. The SMP1302 series of plastic packaged, surface mountable, low capacitance (0.3 pF) silicon PIN diodes is designed for high volume switch and attenuator applications from 10 MHz to beyond 2 GHz. These diodes are designed for use in low- distortion PI and TEE attenuators with low drive current (maximum resistance at 1 mA is 10 Ω) commonly used in TV distribution and cellular base station applications. Features include:

• Nominal 50 μm I region width.
• Maximum resistance of 3 Ω at 10 mA.
• Small footprint SC-79.
• An ultralow inductance (0.2 nH) SOT-143 (SMP1302-017), and miniature SC-70.
