In this paper we study the maximal operators Tδ* and the convolution operators Tδ associated with multipliers of the form. We prove that Tδ* satisfies the sharp weak type (p,p) inequality on Hp(Rn) when 2(n-1)2n-1<p<1 and δ=n(1p-1)+12, or when p=2(n-1)2n-1 and δ>n(1p-1)+12. We also obtain that Tδ is bounded from Lp(Rn) to Lp(Rn) for δ>max{2|1p-12|-12,0} and 1<;p<∞. The indicated ranges of parameters p and δ cannot be improved.
