DATA SHEET • SKY73070 DOWNCONVERSION MIXER  
injection. However, the LO can be driven over a wide frequency  
range with only slight degradation in performance.  
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.  
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.  
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.  
RF Balun and Passive Mixer  
A simple matching network allows the output ports to be matched  
to a balanced 200 Ω 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.  
The RF balun provides a single ended input, which can easily be  
matched to 50 Ω 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 3rd Order  
Input Insertion Point (IIP3).  
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.  
Additionally, the balanced nature of the mixer provides for high  
port-to-port isolation.  
LO Buffer  
Typical performance characteristics for the SKY73070 are  
illustrated in Figures 3 through 18.  
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

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.
