The singular integral operatorTα,βf(x)=p.v.∫R^n[e^i|y|^-βΩ(y’)]/[|y|^n+α]f(x-y)dy,defined for all test functions f is studied, where Ω(y') is a distribution on the unit sphere S^n-1 satisfying certain cancellation condition. It is proved that Tα,β is a bounded operator from the Triebel-Lizorkin space Fp^s,q to the Triebel-Lizorkin space Fp^s+γ,q, provided that Ω(y') is a distribution in the Hardy space H^r(S^n-1) with r = (n - 1)/(n - 1 + γ).
