Mixer output from upconverter.
Mixer output from upconverter.
10 and 11 pins should be externally
equipped with tank circuit of inductor (eg
4.7 nH) and capacitor (eg 3.5 pF).
Ground for oscillator buffer amplifier and
mixer of upconverter.
Must be connected to the system ground
with minimum inductance. Ground
pattern on the board should be formed
as wide as possible.
(Track length should be kept as short as
possible.)
Bypass of IF input for upconverter.
This pin is IF input for upconverter
designed as double balanced mixer.
This high-impedance input should be
externally equipped with matching circuit
of inductor (eg 220 nH) and capacitor
(eg 1.5 pF).
Local oscillator input for upconverter. Re-
quired for matching with register 51
Bypass of local oscillator input for
upconverter.
Bypass of local oscillator input for
downconverter.
Local oscillator input for down-
converter. Required for matching with
register 51
Supply voltage for downconverter.
It must be connected bypass capacitor
(e.g 1 000 pF) to minimize ground
impedance.
IF output from downconverter.
