LT1632/LT1633
TYPICAL APPLICATIONS
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 50โฆ load. This circuit
has a โ 3dB bandwidth from 2MHz to 2GHz and a power
gain of 25dB.
