Functional Description
The SKY73062-11 is a high linearity, single up/downconversion
mixer, optimized for base station receiver applications. The device
consists of a low loss RF balun and high linearity passive mixer.
An LO amplifier is also included that allow the SKY73062-11 to
connect directly to the output of a Voltage Controlled Oscillator
(VCO). This eliminates the extra gain stages needed by most
discrete passive mixers. A Single Pole, Double Throw (SPDT)
switch has been included to select between two different LO
inputs (LO1 and LO2) for frequency hopping applications such as
GSM.
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
balun offers very low loss, and excellent amplitude and phase
balance.
The high linearity SKY73062-11 is a passive, double-balanced
mixer that provides a very low conversion loss, and excellent 3
Order Input Insertion Point (IIP3).
Additionally, the balanced nature of the mixer provides for high
port-to-port isolation.

must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

PRELIMINARY DATA SHEET • SKY73062-11 UP/DOWNCONVERSION MIXER
LO Buffer and SPDT LO Switch
The LO buffer allows the input power of the SKY73062-11 to be in
the range of 6 dBm. The LO section is optimized for high-side
LO injection. However, each of the two LOs can be driven over a
wide frequency range with some degradation in performance.
A high isolation SPDT switch allows the SKY73062-11 to be used
for frequency hopping applications. This switch provides greater
than 40 dB of LO1 to LO2 isolation:
For applications that do not require frequency hopping, LO_SEL is
fixed to one state and the appropriate LO input is used. An internal
pull-down resistor enables the LO2 input.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY73062-11 are provided
in Table 2 and the recommended operating conditions in Table 3.
