RFM P1104
TO39-3 Case
Ideal for 824 MHz Oscillators
Nominal Insertion Phase Shift of 180 at Resonance
Quartz Stability
Rugged, Hermetic, Low-Profile TO39 Case
Complies with Directive 2002/95/EC (RoHS)
The RP1104 is a two-port, 180 surface-acoustic-wave (SAW) resonator in a low-profile TO39 case. It pro-
vides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency oscillators operating at or
near 824.05 MHz. The nominal resonator frequency is higher than the nominal oscillator frequency to allow
for production frequency tuning. This SAW is designed specifically for stabilization of the second LO of CATV
convertors with channel 13 outputs for use in Taipei. In this application, the oscillator must be a modified-
Colpitts design with the SAW connected to simulate a one-port SAW.

Notes:
1.
Frequency aging is the change in f
C
with time and is specified at +65C or less. Aging may exceed the specification for prolonged temperatures
above +65C. Typically, aging is greatest the first year after manufacture, decreasing significantly in subsequent years.
2.
The frequency f
C
is the frequency of minimum IL with the resonator in the specified test fixture in a 50
test system with VSWR
1.2:1. Typically,
f

is less than the resonator f

This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance
C
O
is the measured static (nonmotional) capacitance between either pin 1 and ground or pin 2 and ground. The measurement includes case parasitic
capacitance.

Electrical Connections
This two-port, three-terminal SAW resonator is bidirectional. However, im-
pedances and circuit board parasitics may not be symmetrical, requiring
slightly different oscillator component-matching values.

Electrical Test
This SAW resonator can be used in oscillator or transmitter designs that
require 180 phase shift at resonance in a two-port configuration. One-
port resonators can be simulated, as shown, by connecting pins 1 and 2
together. However, for most low-cost consumer products, this is only
recommended for retrofit applications and not for new designs.
