µ
PC1694GR
GENERAL PURPOSE HIGH FREQUENCY WIDEBAND IC
FOR FREQUENCY DOWN-CONVERTER
DESCRIPTION
The
µ
PC1694GR is Silicon monolithic IC for down-converter that is capable of operating up to 1 GHz.
This IC consists of double balanced mixer (DBM), local oscillator and IF amplifier. Furthermore, combination with
the
µ
PC1663G (high-speed video amp) enables it to be applied to a FM demodulation circuit such as DBS tuner.
The package is 14-pin SOP suitable for surface mounting.
FEATURES
• Satisfactory 1% cross-modulation distortion characteristics: CM = 103 dB
µ
@ f
des
= 200 MHz
• Wide band operation: f
≤
1 GHz
• Easy to connect with varactor diode due to balanced amplifier oscillator
• Single-end push-pull IF amplifier suppresses fluctuation in output impedance
• Supply voltage: 5 V
• Packaged in 14-pin SOP suitable for smaller mounting area
APPLICATIONS
• Tuners for TV and VCR
