DATA SHEET ? SKY73070 DOWNCONVERSION MIXER
Functional Description
The SKY73070 is a high gain single mixer, optimized for base
station receiver applications. The device consists of a low loss RF
balun, high linearity passive mixer, and a low noise IF amplifier.
An LO amplifier is also included that allow the SKY73070 to
connect directly to the output of a Voltage Controlled Oscillator
(VCO). This eliminates the extra gain stages needed by most
discrete passive mixers.
RF Balun and Passive Mixer
The RF balun provides a single ended input, which can easily be
matched to 50 ? using a simple external matching circuit. The RF
balun offers very low loss, and excellent amplitude and phase
balance.
The high linearity SKY73070 is a passive, double balanced mixer
that provides a very low conversion loss, and excellent 3 rd Order
Input Insertion Point (IIP3).
Additionally, the balanced nature of the mixer provides for high
port-to-port isolation.
LO Buffer
An LO buffer allows the input power of the SKY73070 to be in the
range of ± 6 dBm. The LO section is optimized for high-side LO
Table 2. SKY73070 Absolute Maximum Ratings (Note 1)
injection. However, the LO can be driven over a wide frequency
range with only slight degradation in performance.
IF Amplifier
The SKY73070 includes a high dynamic range IF amplifier that
follows the passive mixer in the signal path. The outputs require a
supply voltage connection using inductive chokes. These choke
inductors should be high-Q and have the ability to handle 200 mA
or greater.
A simple matching network allows the output ports to be matched
to a balanced 200 ? impedance. The IF amplifier is optimized for
IF frequencies between 40 and 300 MHz. The IF amplifier can be
operated outside of this range, but with a slight degradation in
performance.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY73070 are provided in
Table 2 and the recommended operating conditions in Table 3.
Electrical characteristics for the SKY73070 are provided in
Table 4.
Typical performance characteristics for the SKY73070 are
illustrated in Figures 3 through 18.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value.
Note 2 : Nominal thermal resistance (junction to center ground pad) is 5.1 ° C/W.
