SA612A
Double-balanced mixer and oscillator
Rev. 3 — 4 June 2014
Product data sheet
1. General description
The SA612A is a low-power VHF monolithic double-balanced mixer with on-board
oscillator and voltage regulator. It is intended for low cost, low-power communication
systems with signal frequencies to 500 MHz and local oscillator frequencies as high as
200 MHz. The mixer is a ‘Gilbert cell’ multiplier configuration that provides gain of 14 dB or
more at 45 MHz.
The oscillator can be configured for a crystal, a tuned tank operation, or as a buffer for an
external LO. Noise figure at 45 MHz is typically below 6 dB and makes the device
well-suited for high-performance cordless phone/cellular radio. The low power
consumption makes the SA612A excellent for battery-operated equipment. Networking
and other communications products can benefit from very low radiated energy levels
within systems. The SA612A is available in an 8-lead SO (surface-mounted miniature
package).

7. Functional description
The SA612A is a Gilbert cell, an oscillator/buffer, and a temperature-compensated bias
network as shown in Figure 3. The Gilbert cell is a differential amplifier (IN_A and IN_B
pins) that drives a balanced switching cell. The differential input stage provides gain and
determines the noise figure and signal handling performance of the system.

Equivalent circuit
The SA612A is designed for optimum low-power performance. When used with the
SA614A as a 45 MHz cordless phone/cellular radio second IF and demodulator, the
SA612A is capable of receiving 119 dBm signals with a 12 dB S/N ratio. Third-order
intercept is typically 15 dBm (that is approximately +5 dBm output intercept because of
the RF gain). The system designer must be cognizant of this large signal limitation. When
designing LANs or other closed systems where transmission levels are high, and
small-signal or signal-to-noise issues are not critical, the input to the SA612A should be
appropriately scaled.
Besides excellent low-power performance well into VHF, the SA612A is flexible. The input,
output and oscillator ports support various configurations provided the designer
understands certain constraints, which are explained here.
The RF inputs (IN_A and IN_B pins) are biased internally. They are symmetrical. The
equivalent AC input impedance is approximately 1.5 k 3 pF through 50 MHz. IN_A and
IN_B pins can be used interchangeably, but they should not be DC biased externally.
Figure 4 shows three typical input configurations.

The mixer outputs (OUT_A and OUT_B pins) are also internally biased. Each output is
connected to the internal positive supply by a 1.5 k resistor. This permits direct output
termination yet allows for balanced output as well. Figure 5 shows three single-ended

Double-balanced mixer and oscillator
The oscillator can sustain oscillation beyond 200 MHz in crystal or tuned tank
configurations. The upper limit of operation is determined by tank ‘Q’ and required drive
levels. The higher the ‘Q’ of the tank or the smaller the required drive, the higher the
permissible oscillation frequency. If the required LO is beyond oscillation limits, or the
system calls for an external LO, the external signal can be injected at OSC_B (pin 6)
through a DC blocking capacitor. External LO should be 200 mV (peak-to-peak) minimum
up to 300 mV (peak-to-peak) maximum.
Figure 6 shows several proven oscillator circuits. Figure 6a is appropriate for cordless
phones or cellular radio. As shown, an overtone mode of operation is utilized. Capacitor
C3 and inductor L1 act as a fundamental trap. In fundamental mode oscillation, the trap is
omitted.

Figure 7 shows a Colpitts varactor tuned tank oscillator suitable for synthesizer-controlled
applications. It is important to buffer the output of this circuit to assure that switching
spikes from the first counter or prescaler do not end up in the oscillator spectrum. The
dual-gate MOSFET provides optimum isolation with low current. The FET offers good
isolation, simplicity, and low current, while the bipolar transistors provide the simple
solution for non-critical applications. The resistive divider in the emitter-follower circuit
should be chosen to provide the minimum input signal that assures correct system
operation.

15. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
15.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
15.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
•
•
•
•
•
•
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus SnPb soldering
15.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

15.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 17) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 7 and 8

times.
