BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC1694GR
GENERAL PURPOSE HIGH FREQUENCY WIDEBAND IC
FOR FREQUENCY DOWN-CONVERTER
DESCRIPTION
The µPC1694GR 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 µPC1663G (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 dBµ @ fdes = 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

NOTE ON CORRECT USE
(1) Since this IC uses high frequency process, care is required against the excessive input of static electricity, etc.
(2) Use the shortest possible wiring for the GND pin.
(3) Use the widest possible earth pattern to avoid increase of ground impedance (because it may cause abnormal
oscillation).
(4) Insert a bypass capacitor for the VCC pin (example: 1 000 pF, 2 200 pF, etc.)
(5) Abnormal oscillation may occur depending on the values of the choke coil and floating capacitance. Therefore,
insert a resistor between the power supply and choke coil. (See the application circuit example.)

purposes in semiconductor product operation and application examples. The incorporation of these circuits,

of the customer. NEC Corporation assumes no responsibility for any losses incurred by the customer or third

• While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
• NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
