A
bandwidth of the intermediate frequency is 0,1-4,0 GHz.
The mixers are designed in the form of a waveguide flange
(similar to product M53202, see above). The signal and
heterodyne inputs are from the opposite side of the flange.
Bias current is supplied using a terminal pin or coaxial
connector.
Its overall dimensions are 20x20x10 mm.
Notes: 1.
On demand the mixer modules can be delivered with a wider
intermediate frequency band (up to 20 GHz), a lower noise
level (up to 2 dB), a decreased heterodyne power (up to
2 mW), a higher signal-heterodyne isolation (up to 30
dB) -request. 2.
On demand the mixer modules can be delivered with increased
shock resistance (up to 20000 g) and special protection
of the channel against moisture. 3.
3. Mixers can be manufactured in the customer's cases
or according to the customer's design.
MONOLITHIC
BALANCED MIXERS
WITH AN INTERMEDIATE FREQUENCY AMPLIFIER
A
bandwidth of the intermediate frequency is 0,1-4,0 GHz.
The design is similar to M53202. The intermediate frequency
output is via a terminal pin or coaxial connector.
Note: 1.
Specific requirements (see notes 1-3, Table 1) can be
discussed and taken into account at the order. An additional
topic of discussion can be the gain factor value.
The
bandwidth of the intermediate frequency is 0,1-4,0 GHz. The
receiver consists of 2 (or 3) coaxially connected waveguide
flanges which contain a monolithic balanced mixer with
an intermediate frequency amplifier (see Table 2) and
a quasi-monolithic heterodyne (or a quasi-monolithic heterodyne
+ a monolithic multiplier). Its overall dimensions are
20x20x20 (or 30) mm. At the customer's order the receiver
can be produced in all-in-one case of the above dimensions.

PASSIVE
WAVEGUIDE NODES
Passive
waveguide nodes (bridges, couplers, polarizers, etc.)
are constructed in the same case based on the parameter
requirements as well as size and weight characteristics
of the whole device. Efficient software is used to calculate
the above nodes.
A
bandwidth of the intermediate frequency is 0,1-4,0 GHz.
The mixers are designed in the form of a waveguide flange
(similar to product M53202, see above). The signal and
heterodyne inputs are from the opposite side of the flange.
Bias current is supplied using a terminal pin or coaxial
connector.
