SA606 Datasheet PDF – Mixer FM IF System

Part Number: SA606

Function: Low-voltage high performance mixer FM IF system

Package: SO 20, SSOP 20 Type

Manufacturer: NXP Semiconductors.

Pinouts:

SA606 datasheet

 

Description

The SA606 is a low-voltage high performance monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic Received Signal Strength Indicator (RSSI), voltage regulator and audio and RSSI op amps. The SA606 is available in SO20 and SSOP20 packages.

The device was designed for portable communication applications and will function down to 2.7 V. The RF section is similar to the famous SA605. The audio and RSSI outputs have amplifiers with access to the feedback path. This enables the designer to adjust the output levels or add filtering.

Let’s take a look at the features of this IC.

1. Low power consumption: 3.5 mA typical at 3 V
2. Mixer input to >150 MHz
3. Mixer conversion power gain of 17 dB at 45 MHz
4. XTAL oscillator effective to 150 MHz
5. 102 dB of IF amp/limiter gain
6. 2 MHz IF amp/limiter small signal bandwidth
7. Temperature compensated logarithmic RSSI with a 90 dB dynamic range
8. Low external component count; suitable for crystal/ceramic/LC filters
7. Audio output internal op amp
8. RSSI output internal op amp
9. Internal op amps with rail-to-rail outputs
10. Latch-up testing is done to JEDEC Standard JESD78 Class II, Level B

Applications:

1. Portable cellular radio FM IF
2. Cordless phones
3. Wireless systems
4. RF level meter
5. Spectrum analyzer
6. Instrumentation
7. FSK and ASK data receivers
8. Log amps
9. Portable high performance communication receiver
10. Single conversion VHF receivers

SA612A Datasheet – Double-balanced Mixer and Oscillator

Part Number: SA612A

Function: Double-balanced mixer and oscillator

Package: 8-lead SO Type

Manufacturer: Philips Electronics ( https://www.nxp.com/ )

Pinouts:

SA612A datasheet

 

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 benefitfrom very low radiated energy levels within systems. The SA612A is available in an 8-lead SO (surface-mounted miniature package).

Features

1. Low current consumption
2. Low cost
3. Operation to 500 MHz
4. Low radiated energy
5. Low external parts count; suitable for crystal/ceramic filter
6. Excellent sensitivity, gain, and noise figure

Applications

1. Cordless telephone
2. Portable radio
3. VHF transceivers
4. RF data links
5. Sonobuoys
6. Communications receivers
7. Broadband LANs
8. HF and VHF frequency conversion
9. Cellular radio mixer/oscillator
