Preliminary
• Designed for Short-Range Wireless Data Communications
• Supports up to 115.2 kbps Encoded Data Transmissions
• 3 V, Low Current Operation plus Sleep Mode
• Ready to Use OEM Module
The DR4101 transmitter module is ideal for short-range wireless data applications where robust operation,
small size and low power consumption are required. The DR4101 utilizes RFM’s TX5001 amplifier-
sequenced hybrid (ASH) architecture to achieve this unique blend of characteristics. The transmitter includes
provisions for on-off keyed (OOK) and ASK modulation. The transmitter employs SAW filtering to suppress
output harmonics, facilitating compliance with FCC 15.249 and similar regulations. The DR4101 includes the
TX5001 plus all configuration components in a ready-to-use PCB assembly, excellent for prototyping and
intermediate volume production runs.

Description
The TX IN pin is connected to the transmitter TXMOD pin through a 4.7 K resistor on the circuit board. Additional series
resistance will often be required between the modulation source and the TX IN pin, depending on the desired output power
and peak modulation voltage (3.3 K typical for a peak modulation voltage of 3 volts). Saturated output power requires about
450 µA of drive current. Peak output power PO for a 3 Vdc supply is approximately:
PO = 4.8*((VTXH - 0.9)/(RM + 4.7))2, where PO is in mW, peak modulation voltage VTXH is in volts and external modulation
resistor RM is in kilohms
This pin must be held low in the receive and sleep modes. Please refer to section 2.9 of the ASH Transceiver Designer's
Guide for additional information.
This is the positive supply voltage pin for the module. The operating voltage range is 2.7 to 3.5 Vdc. It is also possible to use
Pin 1 as the Vcc input. Please refer to the Pin 1 description above.
This is the supply voltage return pin.
CTR1 and CTR0 select the transmit modes. CTR1 high and CTR0 low place the unit in the ASK transmit mode. CTR1 low
and CTR0 high place the unit in the OOK transmit mode. CTR1 and CTR0 both low place the unit in the power down (sleep)
mode. CTR1 is a high-impedance input (CMOS compatible). An input voltage of 0 to 200 mV is interpreted as a logic low. An
input voltage of Vcc - 200 mV or greater is interpreted as a logic high. An input voltage greater than Vcc + 200 mV should not
be applied to this pin. This pin must be held at a logic level; it cannot be left unconnected.
T” =1 for transmission, “S” =0 for sleep mode
RFIO is the RF output pin. A matching circuit for a 50 ohm load (antenna) is implemented on the circuit board between this
pin and the transceiver SAW filter transducer.
This pin is the RF ground (return) to be used in conjunction with the RFIO pin. For example, when connecting the module to
an external antenna, the coaxial cable ground is connected this pin and the coaxial cable center conductor is connected to
RFIO.
