• Alpha SMP1322 Series handbook

  This document introduces the SMP1322 series of plastic packaged PIN diodes from Alpha Industries, Inc. The series features low resistance, high frequency, and multiple package configurations.

• Alpha SMP1321 Series handbook

  The SMP1321 series of plastic packaged, surface mountable PIN diodes are designed for high volume switch applications from 10 MHz to beyond 2 GHz. The low capacitance of these diodes (0.25 pF) combined with its low resistance (2.0 Ω maximum at 10 mA) make the SMP1321 series particularly suited to high isolation series connected PIN diode switches in battery operated circuits. Available in a selection of plastic packages and in a variety of configurations including a low inductance (0.4 nH) SOT-23 (SMP1321-007), the small footprint SC-79 and the miniature SC-70.

• Alpha SMP1320 Series handbook

  The document describes the features and characteristics of the Alpha Industries, Inc. SMP1320 series plastic packaged surface mountable PIN diodes, which are designed for high performance wireless switch applications and have low resistance and low capacitance.

• Alpha SMP1307 Series handbook

  The SMP1307 series of plastic packaged, surface mountable, low capacitance silicon PIN diodes are designed for use in attenuator applications from 5 MHz to beyond 2 GHz. They are suitable for CATV AGC applications and high volume wireless applications, and have a low distortion design.

• Alpha SMP1304 Series handbook

  The SMP1304 series of plastic packaged, surface mountable, low capacitance (0.3 pF) silicon PIN diodes are designed for use in attenuator applications from 5 MHz to beyond 2 GHz.

• Alpha SMV1247 -SMV1255 Hyperabrupt Tuning Varactors handbook

  This document introduces the SMV1247-SMV1255 series of silicon hyperabrupt junction varactor diodes from Alpha Industries, Inc. This family of varactors is characterized for capacitance and resistance over temperature. SPICE models are provided.

• Alpha SMV1232-SMV1237 Hyperabrupt Tuning Varactors handbook

  The SMV1232-SMV1237 series of silicon hyperabrupt junction varactor diodes are designed for use in VCOs with low tuning voltage operation. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz.

• Alpha Plastic Packaged Surface Mount Varactor diodes handbook

  The product is a SMV1247-001 plastic variable capacitor diode produced by Alpha Industries. The product has high Q, abrupt and hyperabrupt junction designs, single, common anode and common cathode configurations, and is available for 3 volt battery operated circuits. The price is suitable for large-scale commercial applications and can be provided in tape and reel, as well as chips.

• Alpha SMV1142-SMV1148 Hyperabrupt Tuning Varactors handbook(2)

• Alpha SMV1129 SMV1139 Hyperabrupt Tuning Varactors handbook

  SMV1129 and SMV1139 are hyperabrupt junction varactor diodes designed for use in VCOs requiring low resistance. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz.

• Alpha SMV1142-SMV1148 Hyperabrupt Tuning Varactors handbook(1)

  The SMV1142–SMV1148 series of silicon hyperabrupt junction varactor diodes are specifically designed with an increasing gamma vs. voltage characteristic. This characteristic will result in improved VCO frequency-voltage linearity, in comparison to a conventional hyperabrupt junction varactor. This family of varactors is characterized for capacitance and resistance over temperature. SPICE models are provided.
