AM/FM-IF/MPX Tuner System for Radio-Casette Recorders, Music Centers

Overview The LA1805 is a characteristics-improved version of the LA1810, with the same pin assignment and package as those of the LA1810. Improvements are made on the following point : • Separation (35dB→48dB) and its dependence on free running frequency (Sep – fF Characteristic on page 4).

Overview\nThe LA1805 is a characteristics-improved version of the LA1810, with the same pin assignment and package as those of the LA1810. Improvements are made on the following point :\n• Separation (35dB→48dB) and its dependence on free running frequency (Sep – fF Characteristic on page 4).\n• FM • FM/AM/MPX functions contained on a single chip.\n• Minimum number of external parts required.\n• On-chip FM muting function.\n• High sensitivity.\n• Less carrier leak of MPX. ;

1.9 GHz POWER AMPLIFIER GaAs MONOLITHIC INTEGRATED CIRCUIT

This two–stage class AB monolithic GaAs amplifier in a low–cost 16 lead plastic package is designed for output or driver applications in 1.9 GHz PCS handsets and basestations. The design is optimized for 3.0 Volt operation in systems such as Japan’s PHS, Europe’s DECT and the emerging North Americ
