PC8172TB
DESCRIPTION
transceiver transmitter stage.
The
µ
PC8172TB is a silicon monolithic integrated circuit designed as frequency up-converter for wireless
This IC is as same circuit current as conventional
µ
PC8106TB, but operates at higher frequency, higher gain and
lower distortion. Consequently this IC is suitable for mobile communications.
FEATURES
• Recommended operating frequency : f
RFout
= 0.8 to 2.5 GHz
• Higher IP

= +7.5 dBm TYP. @ f
RFout
= 0.9 GHz
APPLICATIONS
• PCS1900M
• 2.4 GHz band transmitter/receiver system (wireless LAN etc.)

GND pin. Ground pattern on the
board should be formed as wide
as possible. Track Length should
be kept as short as possible to
minimize ground impedance.

This pin is RF output from DBM.
This pin is designed as open
collector. Due to the high imped-
ance output, this pin should be
externally equipped with LC
matching circuit to next stage.
Power save control pin. Bias

This pin is IF input to double bal-
anced mixer (DBM). The input is
designed as high impedance.
The circuit contributes to sup-
press spurious signal. Also this
symmetrical circuit can keep
specified performance insensitive
to process-condition distribution.
For above reason, double bal-
anced mixer is adopted.
