Radiometrix - Radiometrix - #4

The TX1 and RX1 form a miniature VHF radio transmitter / receiver pair designed for PCB mounting and are suitable for extended range data links at speeds up to 10kbps. Link ranges in excess of 1km are achievable with suitable choice of data

rate and antennas.

NRX1 (SIL) and CVR1 (DIL) are a low cost 25kHz Narrow Band FM VHF receiver modules. These receivers are compatible with all Radiometrix VHF transmitters on the same frequency. These can be used to extended operating range of

applications using wideband SIL and DIL modules.

Custom frequencies: 120-180MHz

Single channel, crystal controlled, narrowband (25kHz) radios

Sensitivity: -120dBm (for 12dB SINAD) Data rates upto 10kbps Supply: 2.9-15V @10mA AF, Digital Baseband and RSSI Double conversion superhetrodyne Receiver spurii, image rejection: > 60dB Adjacent Channel: >70dB, Blocking: >86dB Useable range over 1km depending on Transmitter,

Antenna used

• Dimensions: 33 x 23 x 8mm

• -120dBm sensitivity (for 12dB SINAD)

• Supply: 3V (regulated) @ 7mA

• Receive spurii better than 60dB

• Adjacent Channel: -65dBm, blocking: -85dBm

• Low Cost alternative in BiM1R (dual in line) footprint

• Data rates up to 10kbps (standard module)

The TX1H transmitter modules offer a 100mW RF output VHF data link in Radiometrix SIL standard pin-out and footprint. This makes the TX1H ideally suited to those low power applications where existing narrow band and wideband transmitters provide insufficient range. The special HX1 transmitter modules offer a 300mW RF output VHF data link in Radiometrix SIL standard pin-out and footprint.Together with the matching RX1 or BiM1R receiver a one-way radio data link can be achieved over a distance up to 10km+ with suitable choice of data rate and antennas.
