An apparatus for producing a plurality of pilot signals corresponding to a multi-frequency assignment (FA) of a small-capacity base transceiver station supporting only the primary frequency assignment (FA1) to perform a hand-off in a CDMA communication system which supports the multi-frequency assignment (FA). The apparatus includes a first phase locked loop (PLL) synthesizer having a first PLL for synthesizing the primary frequency assignment (FA1) signal by controlling the first PLL, a second PLL synthesizer having a second PLL for synthesizing the multi-frequency assignment (FA) signals by controlling the second PLL, and an up-converter for modulating the transmission data with the primary frequency assignment signal provided from the first PLL synthesizer and producing the pilot signals corresponding to the multi-frequency assignment by modulating a signal, prior to RF modulation, with the multi-frequency assignment signals provided from the second PLL synthesizer.
