CHC2442-QPG
24GHz ISM SENSOR
Monolithic Microwave IC in SMD leadless package
Description
The CHC2442-QPG is a multifunction chip
which integrates a low phase noise VCO, Tx
MPA, two Gilbert based heterodyne Rx and a
switchable prescaler. The circuit is controlled
by SPI and monitored with power and
temperature sensor.
It is designed for signal generation and
reception for automotive radar applications.
It is supplied in RoHS compliant SMD
package.

Voltage applied through external serial resistor to limit V_TUNE current below 9mA DC.
Device thermal performances
All the figures given in this section are obtained assuming that the QFN device is cooled
down only by conduction through the package thermal pad (no convection mode
considered).
The temperature is monitored at the package back-side interface (TCase) as shown below.
The system maximum temperature must be adjusted in order to guarantee that TCase remains
below than the maximum value specified in the next table. So, the system PCB must be
designed to comply with this requirement.

SPI
The digital input should use standard 4-wires synchronous serial peripheral interface (SPI)
with data read and write capabilities. The SPI has hardwired Power-On Reset, such that the
output bits for Control Bus will be set to default state (low power mode) after turning on 3.3V
supply. Data transmission is enabled by negative edge of CS (Chip Select) and serial data
input (SI) are then read at the rising edge of CLK (SPI Clock). The timing diagram in the next
picture describes the principle of the SPI timing and handling between shift and storage
register.
