Lansdale Semiconductor is known for its support of hard-to-find devices and semiconductors and, this past year, added several RF integrated circuits (RFICs) to its product lineup. Backed by their Tempe, AZ wafer fabrication facility, the company now has single-source rights to produce several RFICs originally developed by Freescale Semiconductor, including the model MC1350 intermediate-frequency (IF) amplifier, the MC1490 RF amplifier, and MC1590 IF amplifier. This support by Lansdale assures a continuous source of these high-performance ICs to commercial, defense/military/aerospace, and telecommunications industries.
The RoHS-compliant building-block models MC1350 and MC1490 feature automatic gain control (AGC) and are suitable for IF applications to 70 MHz. The model MC1490 RF amplifier operates over the full military temperature range and is a direct-coupled amplifier designed for applications to 150 MHz. It is supplied in an eight-pin TO-99 metal package.
