Evaluation
Module
The DR7000-EV hybrid transceiver module is ideal for short-range wireless data applications
where robust operation, small size, low power consumption and low cost are required. The
DR7000-EVDR7000-EV utilizes RFM’s TR7000 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 DR7000-EV is sensitive and sta-
ble. A wide dynamic 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 stag-
es of SAW filtering provide excellent receiver out-of-band rejection. The transmitter includes pro-
visions for both on-off keyed (OOK) and amplitude-shift keyed (ASK) modulation. The transmitter
employs SAW filtering to suppress output harmonics, facilitating compliance with ETSI I-ETS 300
220 and similar regulations.
