SA58640  
Low-voltage mixer FM IF system  
Rev. 01 — 6 April 2005  
Product data sheet  
1. Introduction  
The SA58640 was designed for cordless telephone applications in which efficient and  
economic integrated solutions are required and yet high performance is desirable.  
Although the product is not targeted to meet the stringent specifications of high  
performance cellular equipment, it will exceed the needs for analog cordless phones. The  
minimal amount of external components and absence of any external adjustments makes  
for a very economical solution.  
2. General description  
The SA58640 is a low-voltage monolithic FM IF system incorporating a mixer/oscillator,  
two limiting intermediate frequency amplifiers, quadrature detector, logarithmic RSSI,  
voltage regulator and audio and RSSI opamps. The SA58640 is available in a 20-pin  
SSOP package.  
3. Features  
Low power consumption: 5.0 mA typical at 5 V  
Mixer input to >100 MHz  
Mixer conversion power gain of 17 dB at 45 MHz

at higher frequencies)  
102 dB of IF amp/limiter gain  
2 MHz IF amp/limiter small signal bandwidth  
Temperature compensated logarithmic RSSI with a 70 dB dynamic range  
Low external component count; suitable for crystal/ceramic/LC filters

8. Functional description  
The SA58640 is an IF signal processing system suitable for second IF systems with input  
frequency as high as 100 MHz. The bandwidth of the IF amplifier and limiter is at least  
2 MHz with 90 dB of gain. The gain/bandwidth distribution is optimized for 455 kHz,  
1.5 ksource applications. The overall system is well-suited to battery operation as well  
as and high quality products of all types.  
The input stage is a Gilbert cell mixer with oscillator. Typical mixer characteristics include  
a noise figure of 7.0 dB, conversion gain of 17 dB, and input third-order intercept of  
10 dBm. The oscillator will operate in excess of 100 MHz in LC tank configurations.  
Hartley or Colpitts circuits can be used up to 100 MHz for crystal configurations.  
The output impedance of the mixer is a 1.5 kresistor permitting direct connection to a  
455 kHz ceramic filter. The input resistance of the limiting IF amplifiers is also 1.5 k. With  
most 455 kHz ceramic filters and many crystal filters, no impedance matching network is  
necessary. The IF amplifier has 44 dB of gain and 5.5 MHz bandwidth. The IF limiter has  
58 dB of gain and 4.5 MHz bandwidth. To achieve optimum linearity of the log signal  
strength indicator, there must be a 12 dB(V)1 insertion loss between the first and second  
IF stages. If the IF filter or interstage network does not cause 12 dB(V) insertion loss, a  
1. dB(V) = 20log Vo/Vi.

SA58640  
Philips Semiconductors  
Low-voltage mixer FM IF system  
fixed or variable resistor or an L pad for simultaneous loss and impedance matching can  
be added between the first IF output (pin 16) and the interstage network. The overall gain  
will then be 90 dB with 2 MHz bandwidth.  
The signal from the second limiting amplifier goes to a Gilbert cell quadrature detector.  
One port of the Gilbert cell is internally driven by the IF. The other output of the IF is  
AC-coupled to a tuned quadrature network. This signal, which now has a 90° phase  
relationship to the internal signal, drives the other port of the multiplier cell.  
The demodulated output of the quadrature drives an internal opamp. This opamp can be  
configured as a unity gain buffer, or for simultaneous gain, filtering, and 2nd-order  
temperature compensation if needed. It can drive an AC load as low as 10 kwith a  
rail-to-rail output.  
A log signal strength indicator completes the circuitry. The output range is greater than  
70 dB and is temperature compensated. This signal drives an internal opamp. The opamp  
is capable of rail-to-rail output. It can be used for gain, filtering, or 2nd-order temperature  
compensation of the RSSI, if needed.

[1] The generator source impedance is 50 , but the SA58640 input impedance at pin 18 is 1500 . As a result, IF level refers to the actual  
signal that enters the SA58640 IF amplifier input (pin 18) which is about 21 dB less than the ‘available power’ at the generator.

Low-voltage mixer FM IF system  
1. The C-message and de-emphasis filter combination has a peak gain of 10 for  
accurate measurements. Without the gain, the measurements may be affected by the  
noise of the scope and HP339A analyzer. The de-emphasis filter has a fixed  
6 dB/Octave slope between 300 Hz and 3 kHz.  
2. The ceramic filters can be 30 kHz SFG455A3s made by Murata which have 30 kHz IF  
bandwidth (they come in blue), or 16 kHz CFU455Ds, also made by Murata (they  
come in black). All specifications and testing are done with the wideband filter.  
3. Set your RF generator at 45.000 MHz, use a 1 kHz modulation frequency and a 6 kHz  
deviation if you use 16 kHz filters, or 8 kHz if you use 30 kHz filters.  
4. The measured typical sensitivity for 12 dB SINAD should be 0.45 µV or 114 dBm at  
the RF input.  
5. The layout is very critical in the performance of the receiver. We highly recommend  
our demo board layout.  
6. The smallest RSSI voltage (i.e., when no RF input is present and the input is  
terminated) is a measure of the quality of the layout and design. If the lowest RSSI  
voltage is 500 mV or higher, it means the receiver is in regenerative mode. In that  
case, the receiver sensitivity will be worse than expected.  
7. All of the inductors, the quad tank, and their shield must be grounded. A 10 µF to  
15 µF or higher value tantalum capacitor on the supply line is essential. A low  
frequency ESR screening test on this capacitor will ensure consistent good sensitivity  
in production. A 0.1 µF bypass capacitor on the supply pin VCC, and grounded near  
the 44.545 MHz oscillator improves sensitivity by 2 dB to 3 dB.  
8. R5 can be used to bias the oscillator transistor at a higher current for operation above  
45 MHz. Recommended value is 22 k, but should not be below 10 k.
