temperature range. The op amp A1 combined with Q1, Q2,

R1, R2 and R3 establishes two current sources of 21.5mA

to bias RF1 and RF2 amplifiers. The current of Q1, is

determined by the voltage across R2 over R1, which is

then replicated in Q2. These current sources are stable and

precise over temperature and have a low dissipated power

due to a low voltage drop between their terminals. The

amplifier A2 is used to restore the DC level at the output.

With a large output current of the LT1632, the output can

be set at 1.5V DC on 5V supply and 50

Ω load. This circuit

has a – 3dB bandwidth from 2MHz to 2GHz and a power

gain of 25dB.
