US government bonds that mature within 1 to 3 years with a yield of at least 4% per annum? - index of/ mature

I want to invest in bonds in the United States directly (only the index-linked bonds issued by the Government) and without the inclusion of values that are indirectly related to bonds of the United States, but only for the government.

When I am in search of government bonds, anything I could have any other assets like mutual funds that can invest in government bonds and ETNS ETF and investing in government bonds d, but not the bonds.
Not all the other values that are indirectly linked government bonds have support, but only in the purchase of government bonds themselves.
Ultimately that's what) is the symbol of the trade (identification numbers of the bonds themselves?
I am looking for bonds with a remaining term of the United States, 1 to 3 years with an annual coupon rate of return of at least 4%.

Can you please list the stock symbols (identifiers) Consumer Price Index from the U.S. government bonds with interest at a fixed interest rate of 4% at least one years?
