The BT27 is a two stage “SAW”
controlled data transmitter module
operating on the 433.05-434.79 MHz
ISM band.
The module has a high ( 15mW ) output
RF power to allow the employ of poor
efficiency antennas ( ¼ wave whip,
helical or a trace on a PCB) to remain
under the legal 10mW ERP limit. The
BT27A version is OOK modulated
whereas the BT27S employs an
advanced ASK Gaussian shaped ( GASK )
modulation with a speed rate up to
38.4 KB.

HIGH POWER (+14 dB ).
FAST DATA RATE ( 19.2 KB ).
DESCRIPTION:
The New S version, 3rd Series, Xtal controlled
miniaturized 433 MHz SRD Tx.
The BT37S module is a complete transmitter
module, FM or FSK modulated and crystal
controlled on up to 35 different frequency
channels in the 433 MHz band.
The carrier frequency is generated by a fixed
division, low noise PLL integrated circuit (IC1).A
Power Amplifier (P.A.) stage brings the RF
output to the required power level.
FSK Digital (TXD Input) of FM Analog (AIN Input)
modulation to the D1 Varicap Diode (X1 Crystal
Reference Modulation). A 5 poles Low Pass
Filter attenuates the harmonicemissions under
the EN 300-220 limits. The module needs a
single 5VDC supply (Bt37S5) or 3VDC supply
(BR37S3).

DATA TRANSMISSION PROTOCOL:
The “Reference Frequency” modulation scheme allows for a
flat response down to DC levels to avoid loss of balance in the
transmitted signal even in presence of non symmetrical data
patterns.
In data transmission (FSK modulation) nominal frequency
deviation is obtained with a TXD signal level ranging from Zero
to Vs (5V or V3).
Output RF carrier frequency, as adjusted by CV1, corresponds
to F0 center channel frequency when TXD and AIN inputs are
open state or when mean modulation signal level is VS/2.

DESCRIPTION:
The BT38S module is a complete
transmitter module, “FM” or “FSK”
modulated and crystal controlled on up to
35 different frequency
channels in the 868 - 870 MHz band.
The carrier frequency is generated by a
fixed division, low noise “PLL” integrated
circuit (IC1). A Power Amplifier (P.A.) stage
brings the
RF output to the required power level.
“FSK” Digital (TXD Input) of “FM” Analog
(AIN Input) modulation to the D1 Varicap
Diode (X1 Crystal Reference Modulation).
A 5 poles Low Pass Filter attenuates the
harmonic emissions under the EN 300-22o
limits. The module needs a single 5VDC
supply
(Bt38S5) or 3VDC supply (BR38S3).

controlled
synthesized architecture, the BT57 F has
a 20mW RF output power ( 15 mW for
