CYWUSB6935 LR Radio
The CYWUSB6935 provides a complete SPI-to-antenna radio
modem.The CYWUSB6935 is designed to implement wireless
devices operating in the worldwide 2.4-GHz Industrial, Scien-
tific, and Medical (ISM) frequency band (2.400 GHz–2.4835
GHz). It is intended for systems compliant with world-wide
regulations covered by ETSI EN 301 489-1V1.4.1, ETSI EN
300 328-1 V1.3.1 (European Countries); FCC CFR 47 Part 15
(USA and Industry Canada) and ARIBSTD-T66 (Japan).
The CYWUSB6935 contains a 2.4-GHz radio transceiver, a
GFSK modem, and a dual DSSS reconfigurable baseband.
The radio and baseband are both code- and frequency-
agile.Forty-nine spreading codes selected for optimal perfor-
mance (Gold codes) are supported across 78 1-MHz channel
yielding a theoretical spectral capacity of 3822 channels.
FCC cerification and performance is valid only up to power
level PA5. It is advised not to use the module in levels PA6 and
PA7.
Functional Overview
3.2
For the most effective and power efficient communication with
the LR + PA radio module, external antenna INPAQ
DAMA0BM12410205 (Antenna-A) is recommended to be
used with the module.
It is a dipole antenna module, with A0 type appearance. It is a
high frequency coaxial cable type antenna. The operating
frequency range is 2.4 - 2.483 GHz and has a typical
impedance of 50 ohms. The antenna has near omni-direc-
tional radiation pattern in the horizontal plane with a vertical
polarization.
The antenna has an operating range of -20 C - 60 C and can
be stored between -40 C - 80 C.
2.4GHz A0 Type Dipole Antenna
3.3
An efficienct silicon-germanium power amplifier IC, the
PA2423L is designed specifically for wireless applications in
the 2.4GHz ISM band and well suited for WirelessUSB appli-
cations.
PA2423L SiGe Power Amplifier
It has 45% power add efficiency. It is capable of overcoming
insertion losses of up to 2.5db, between the amplifier output
and antenna input.
It also consists of analog and digital control input to control the
analog input for improving the power added efficiency, and the
power up and power down modes respectively.

2.4-GHz DSSS Radio SoC such as register settings, timing,
application interfaces, clocking, and power management, refer
to the data sheet of the CYWUSB6935 Radio SoC.
Reference Documentation
3.5
The CYWM6935PAEC is available as a reference design,
complete with PCB layout files, schematics, and a bill of
materials. The CYWM6935PAEC can be used with the
CY3635 WirelessUSB N:1 sensor development kit, and the
CY3632 WirelessUSB LS development kit using a proper
adapter.
