µPC2794GS
FREQUENCY DOWN CONVERTER FOR
VHF TO UHF BAND TV/VCR TUNER
DESCRIPTION
The µPC2794GS is a Silicon monolithic IC designed for TV/VCR tuner applications. This IC consists of a double
balanced mixer (DBM), local oscillator, preamplifier for precscaler operation, IF amplifier, regulator, UHF/VHF
switching circuit, and so on. This one-chip IC covers a wide frequency band from VHF to UHF bands. This IC is
packaged in 20-pin SOP (Small Outline Package) suitable for surface mounting.
FEATURES
• VHF to UHF bands operation.
• Low distortion CM: VHF (@fRF = 470 MHz) 96 dBµ
UHF (@fRF = 890 MHz) 92 dBµ
• Supply voltage : 9 V
• Packaged in 20-pin SOP suitable for surface mounting
