HMC681LP5 / 681LP5E
v03.1010
Functional Diagram
Electrical Specifications, T
A = +25° C, Vdd = Vs= P/S= +5V
the HmC681lp5(e) is ideal for:
if & rf applications
Cellular/3g infrastructure
Wibro / WimaX / 4g
microwave radio & Vsat
test equipment and sensors
+13.5 db to +45 db gain Control in 0.5 db steps
High Output ip3: +36 dbm
±0.25 db typical gain step error
single +5V supply
32 lead 5x5mm smt package: 25mm2
the HmC681lp5(e) is a digitally controlled variable
gain amplifier which operates from dC to 1 gHz,
and can be programmed to provide anywhere from
13.5 db, to 45 db of gain, in 0.5 db steps. the
HmC681lp5(e) delivers noise figure of 2.8 db in its
maximum gain state, with output ip3 of up to +36
dbm in any state. this serially controlled digital Vga
incorporates off chip aC ground capacitors for near
dC operation, making it suitable for a wide variety of
rf and if applications. the HmC681lp5(e) is housed
in a roHs compliant 5x5 mm Qfn leadless package,
and provides the user with a highly integrated solution.
this functionality is also available with parallel control
as the HmC626lp5(e).
