•
3 V, Low Current Operation plus Sleep Mode
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 sensitive 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 interference 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 output harmonics.
