FUNCTIONAL DESCRIPTION Mixer
TDA1574
The mixer circuit is a double balanced multiplier with a preamplifier (common base input) to obtain a large signal handling range and a low oscillator radiation. Oscillator The oscillator circuit is an amplifier with a differential input. Voltage regulation is achieved by utilizing the symmetrical tanh-transfer-function to obtain low order 2nd harmonics. Linear IF amplifier The IF amplifier is a one stage, differential input, wideband amplifier with an output buffer. Keyed AGC The AGC processor combines narrow- and wideband information via an RF level detector, a comparator and an ANDing stage. The level dependent, current sinking output has an active load, which sets the AGC threshold. The AGC function can either be controlled by a combination of wideband and narrowband information (keyed AGC), or by a wideband information only, or by narrowband information only. If only narrow-band AGC is wanted pin 3 should be connected to pin 5. If only wideband AGC is wanted pin 12 should be connected to pin 13.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
TDA1574
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds.
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale.
