RFM offers a full set of custom embedded wireless networking solutions like Zigbee wireless mesh sensor networks, RF modules, IC transceiver, IC transmitters and IC receivers. RFM, Inc. manufactures low power wireless and RF radio modules, wireless mesh nodes for distributed sensing on distributed sensor networks. Low Power radio, n../arrowband and short range devices, front end saw filters, active RFID, RFIC, coupled resonator filters, single silicon chips in the 70MHZ and 300-1000Mhz range.
The TR3005 ultra-miniature hybrid transceiver is ideal for short-range wireless medical data ap -
plications where robust operation, small size, low power consumption and low cost are required.
The TR3005 employs RFM’s amplifier-sequenced hybrid (ASH) architecture to achieve this
unique blend of characteristics. All critical RF functions are contained in the hybrid, simplifying
and speeding design-in. The receiver section of the TR3005 is sensi tive and stable. A wide dy -
namic range log detector, in combination with digital AGC and a compound data slicer, provide
robust performance in the presence of on-channel in terference or noise. Two stages of SAW fil -
tering provide excellent receiver out-of-band rejection. The transmitter includes provisions for
both on-off keyed (OOK) and amplitude-shift keyed (ASK) modulation. The transmitter employs
SAW filtering to suppress out put harmonics.
