产品描述 (功能) : 315MHz Low-Power, +3V Superheterodyne Receiver

General Description
The MAX1470 is a fully integrated low-power CMOS superheterodyne receiver for use with amplitude-shift keyed (ASK) data in the 315MHz band.

The chip consists of a 315MHz low-noise amplifier (LNA), an image rejection mixer, a fully integrated 315MHz phase-lock-loop (PLL), a 10.7MHz IF limiting amplifier stage with received-signal-strength indicator (RSSI) and an ASK demodulator, and analog baseband data-recovery circuitry.
The MAX1470 is available in a 28-pin TSSOP package.

产品描述 (功能) : 315MHz/433MHz Low-Noise Amplifier for Automotive RKE

General Description
The MAX2634 low-noise amplifier (LNA) with low-power shutdown mode is optimized for 315MHz and 433.92MHz automotive remote keyless entry (RKE) applications. At 315MHz, the LNA achieves 15.5dB power gain and a 1.25dB noise figure while only con suming 2.5mA of supply current from a 2.2V to 5.5V power supply. An integrated logic-controlled low-power shutdown mode reduces power consumption to 0.1µA and replaces the two transistors typically required to implement the shutdown function in discrete-based RKE LNA solutions. The device further reduces component count by integrating the output matching and DC blocking components, and only requires a single inductor to match the input for best noise figure and input return loss

Features
♦ Optimized for 308MHz, 315MHz, 418MHz,
and 433.92MHz
♦ 2.2V to 5.5V Supply Voltage Range
♦ Low Operating Supply Current
2.5mA (typ), 4mA (max)
♦ Logic-Controlled 1µA (max) Shutdown
♦ Typical Performance at 315MHz
    1.25dB Noise Figure
    -16dBm Input IP3
    15.5dB Power Gain
♦ Automotive Temperature Range -40°C to +125°C
♦ ESD Rating of ±2.5kV (HBM) on All Pins

产品描述 (功能) : 315MHz/390MHz Dual-Frequency ASK Transmitter

General Description
The MAX7058 UHF transmitter alternately transmits ASK/OOK data at 315MHz or 390MHz using a single crystal. The MAX7058 has internal tuning capacitors at the output of the power amplifier that can be programmed for matching to the antenna or load. The MAX7058 can transmit at a data rate up to 100kbps NRZ (50kbps Manchester coded). Typical transmitted power into a 50Ω load is +10dBm. The MAX7058 operates from +2.1V to +3.6V and draws under 8.0mA of current. The standby current is less than 1μA at room temperature. A 15MHz crystal is used as the reference for 315MHz and 390MHz operation by selecting synthesizer-divide ratios of 21 and 26, respectively.

Features
♦ Switched 315MHz/390MHz Carrier Frequency Using One Crystal
♦ +2.1V to +3.6V Single-Supply Operation
♦ ASK/OOK Modulation

Mallory performance club
产品描述 (功能) : INLINE FUEL Filter

INLINE FUEL Filter

1. This Filter is supplied with a 40 micron pleated stainless steel Filter disc suitable for use as a pre-Filter for Mallory fule pumps or as a Filter to protect carburetors.
2. Fuel flow can be either direction through the Filter.
3. This Filter may be used to Filter gasoline or alcohol or any other type of petroleum based fuel.
4. Maximum recommended flow is 500 gallons per hour for a clean Filter. The larger the flow, the more frequent the Filter disc must be cleaned.
5. In most cases, the Filter disc can be cleaned and reused indefinitely. To clean the Filter disc, back flush the Filter by flowing fuel in the opposite direction of normal flow into a bucket. This will remove most types of debris. If the debris refuses to come out, the Filter disc can be replaced.
6. This Filter is supplied with a fitting that will screw directly into the inlet of a Mallory 250, 110FI, or 160FI pump so that the Filter functions as a pre-Filter. Alternative fittings may be used to mount the Filter in other types/sizes of fuel lines.
